Miley Cyrus play fights with Avril Lavigne on Instagram video

She is arguably the most famous singer in the world right now.

And Miley Cyrus seems determined to keep it that way.

In new pictures and a video posted to Instagram, Miley is seen attacking fellow pop star Avril Lavigne after the pair argue about which of them is 'the most famous person in Canada'.

In the video, posted by Miley, 20, on Tuesday, she wears a Marijuana onesie.

She is seen reading a magazine with a paper stuck to the front showing Avril, 29, with the words 'the most famous beautiful and popular in Canada' scrawled in black pen, as well as 'I heart' and a picture of a marijuana leaf.

Miley, who is currently in Canada for her Bangerz world tour, looks indignant that she isn't given the 'most famous' title.

'I mean I'm in f**king Canada,' she says.

Avril then walks in and strides up to the star.

'Oh hey Miley, I'm actually the most famous person in Canada,' says the Ontario native. 

Miley then jumps up and protests, stating, 'I'm the most famous person in Canada, you dumb f**king b**ch'.

The pair then start play fighting. 'F**k you,' shouts Miley. 

Avril famously came out in support of Miley's controversial VMA performance last year, stating:

'It's actually really funny cause my managers also manage her. She is doing her thing right now and she is kicking a**, so good for her.'

'We're going pretty big': Avril Lavigne reveals details on her upcoming wedding with Nickelback frontman Chad Kroeger

Avril Lavigne says her upcoming wedding is going to be 'quite spectacular'.

The 28-year-old Canadian star – who was previously married to Sum 41 frontman Deryck Whibley – has admitted she is planning a very lavish big day with her Nickelback rocker fiancé Chad Kroeger and plans to surprise him with a few romantic details.

In a joint interview with Chad on Tuesday, the 'What The Hell' singer told KIIS-FM's On-Air with Ryan Seacrest: 'It's going to be quite spectacular, and there's a theme to it.

'We're going pretty big, but Chad doesn't even know everything.

'I'm going to take the lyrics from the sheet music from one of our songs and wrap it around the wedding cake.'

Avril also opened up about how Chad, 37, proposed to her with a 14-carat diamond ring last August, after just one month of dating.

She said: 'I had been making this scrapbook of my time in the studio. I walk over and he had taken a photo of himself holding the ring box and put the Polaroid in my scrapbook. Because I had stickers everywhere he put in 'Will you marry me?' It was really romantic and kind of made sense.'

Chad revealed he was very nervous beforehand.

He explained: 'You can travel the world and sing songs to thousands of people and not have your heartbeat raised at all. You get down on one knee and commit yourself to a woman for the rest of your life. I was very nervous!'

The singer previously admitted he never expected to get married but meeting Avril changed his mind.

He added: 'There was a time in my life that I thought I would never get married. But this definitely took me by storm. Honestly, it was more my idea than hers to get married. I'm just lucky she said yes.'

The happy couple spent their Sunday together as well, on the Los Angeles set of 28-year-old singer's new music video shoot.

Her new song, aptly titled Here’s to Never Growing Up, had the songstress in a childlike dress that she layered over rhinestone-adorned fishnet stockings.

She teamed the look with a pair of red pumps, which she later switched for some more comfortable black fuzzy boots. 

It looked as if Avril was playing dress up in her mother’s old prom dress and she had her long blonde hair out and matted.

A crown sat on top of her head and pitch-black eyes stared out from between her part.

Heavy eye makeup has always been a part of Avril’s ensemble, but she took it to the extreme for her shoot, almost resembling a racoon. 

The singer was cheerful despite her goth-like makeup, though.

Her fiancé acted as moral support on set, beaming next to her on the backseat of a golf cart.

The pair got engaged in August of 2012 and seem to be even more in love than ever.

Avril Lavigne Engagement Ring 'Worth $350,000'

Avril Lavigne's engagement ring is reportedly worth a cool $350,000.

Following the shock announcement that Lavigne had accepted Nickelback frontman Chad Kroeger's marriage proposal, it has now emerged that the rocker splashed a lot of cash on the ring.

Speaking of the sparkler, jewellery expert Michael O'Connor told US Weekly: "A pear shape diamond set in platinum is a nod to vintage glamour and individuality - perfect for a rocker like Avril.

"The half-moon diamonds are also rare since they would have to be specially cut to fit on either side of the centre diamond. The centre diamond is approximately 10 carats, with an additional four carats of total side diamonds."

The couple have since been spotted celebrating their engagement in Las Vegas, with reports claiming they knocked back bottles of champagne and vodka at the 1OAK nightclub.

An onlooker told Life & Style magazine: "They went to 1 Oak Nightclub in Las Vegas on Aug. 21 to celebrate their engagement.

"Avril arrived first with a bunch of male friends and bodyguards, then Chad showed up later and met them inside. Avril was so excited to see her man.

"They were super cuddly and affectionate. They drank Dom Pérignon and Grey Goose.'She can pound the vodka."

Despite the initial surprise that the 27-year old had become engaged to Kroeger, pals have since told People that they are the perfect match.

The insider said: "They have the same values and really understand each other. They complement each other and are so happy."

Avril and Chad have since spoken of their engagement in an interview with HELLO! Canada, where Kroeger revealed: "I knew I was falling for her. It was incredibly powerful and something I'll never forget."

Lavigne - who was previously married to Sum 41 star Deryck Whibley - added: "He makes me laugh every day. He takes care of me in every way and is extremely attentive."

Avril Lavigne engaged to Nickelback frontman Chad Kroeger

It's a match made in Canadian music heaven as Avril Lavigne and Nickelback frontman Chad Kroeger announce their engagement. The Canadian musicians have been quietly dating for six months. Initially the pair were work colleagues, as Chad and Avril began collaborating on a track for the songstress's upcoming fifth album in February. 

The couple's relationship quickly escalated from friendship to love. "A romantic relationship blossomed as they spent time writing together," a source told People magazine. Chad, 37, apparently presented Avril, 27, with a 14-carat diamond ring when he proposed. According to insiders, the couple couldn't be more thrilled. "He makes her so happy," a source close to the family revealed. "Both of their families could not be more excited."

Chad has never been married before but this will be the second time Avril has walked down the aisle. Avril and her husband of three years - Sum 41 musician Deryck Whibley - divorced in 2009. Avril has most recently dated Brody Jenner but their relationship ended earlier this year. 

Avril Lavigne donates musical instruments to kids

Singer Avril Lavigne has donated musical instruments to a children`s hospital in California.

Lavigne went to the Mattel Children`s hospital in Ucla, California, last month and took some musical instruments along with her for the children to learn while they recover, reports contactmusic.com.

The 27-year-old singer and her musician pal Evan Taubenfeld helped teach their young proteges the basics.

Lavigne shared her excitement on Twitter.

"EvanT giving impromptu guitar lesson (at) UclaHealth Mattel Children`s! We just donated instruments 2 them (sic)," she tweeted.

"Thank you EvanT for helping The Avril Foundation donate instruments (at) Ucla Health Mattel Children`s," she added.

Lavigne had earlier visited the facility in April, and had met the kids in the wards and even performed for them.

Avril Lavigne's half-shaved hairdo

Pop star Avril Lavigne showed her wild side by making an appearance with a partly-shaven head.

The 27-year-old was in Paris to promote her fashion range Abbey Dawn, and she stunned fans with her new hairstyle, reports dailystar.co.uk.

The singer sported a punk style, with one side of her head clipped close to the scalp.

Lavigne follows in the footsteps of Rihanna, Kesha and Madonna's daughter Lourdes, who have all gone for the hairdo in recent months.

Could Miley, Demi or Avril become an 'X Factor' judge?

We know that Simon Cowell is looking for a few good women to join his "X Factor" judges' table, and there's a fresh batch of rumored names being added to the mix.

According to reports, the reality show king is said to be eyeing Avril Lavigne, Miley Cyrus, Gwen Stefani and Demi Lovato for one of the open judging positions, in addition to also reportedly trying to seal a deal with Britney Spears.

E! reports that Cyrus is among the stars in consideration to join Cowell and L.A. Reid on the star-studded panel, but a source tells the site that she hasn’t received an official offer.

But she may have some competition for it: the Hollywood Reporter suggests Lovato is already in final negotiations to star on the show.

Spears, meanwhile, is thought by some to be a shoo-in for the third seat with a reported $15 million offer - although an official announcement has not yet been made.

Spears is the last holdover from the earlier round of names that the media batted about as potential "X Factor" judges, following the dismissal of season 1 personalities Nicole Scherzinger and Paula Abdul.

Cowell's got a little time to see who wins the battle of the divas though: the second season of the talent competition is not expected to kick off until September.

Avril Lavigne, David Guetta and Demi Lovato Rock Y100's Jingle Ball 2011

While New York hosted Z100's Jingle Ball at its famed venue, Madison Square Garden on December 9, Florida was made merry with a similar holiday gig by Y100 on the next day. Avril Lavigne was one of the performers, and David Guetta as well as Demi Lovato, fresh off their headlining bill at the Big Apple concert, flew to the state to help spread the Christmas cheers.

Rocker chick Avril rocked a black cropped top, a pair of skinny leather pants as well as black-and-red heeled boots. Performing songs including the ones from her latest studio installment "Goodbye Lullaby", the girlfriend of Brody Jenner showed off acrobatic stage act at one point during the December 10 concert.

French disc jokey David kept the party going from behind his turntable by spinning a bunch of electro/dance beats. Lovato, meanwhile, alternated her set between pumping up the crowd with uplifting songs and slowed it down with the ballad melody of "Skyscraper". During one of her high-energy sets, she's accompanied by astronaut-helmed dancers.

Off stage, Lovato talked about her duet with Kelly Clarkson at the Z100 concert. To JustJared, she gushed, "She actually was backstage and she was like 'we should sing a duet together' and I was like 'of course, anything you want.' And then we basically came up with the idea to sing a Christmas carol together and it came in place yesterday. It was amazing, I was so excited."

The star-studded annual event took place at the Bank Atlantic Center in Sunrise. The other musical guests at the Saturday night festive event included Flo Rida, Cobra Starship, Gym Class Heroes, Neon Hitch and Karmin.

A CHICAGO man stabbed his mother to death then doused her body in chemicals after she refused to buy him tickets to an Avril Lavigne concert, a jury found.

Robert Lyons, 39, was found guilty of first-degree murder yesterday after a weeklong trial, the Chicago Tribune reported.

Prosecutors said that Lyons began to argue with his mother, Linda Bolek, when she refused to call a friend to arrange tickets for the concert in 2008.

Lyons stabbed his mother nine times in the back, then poured insecticide and drain cleaner on her body, prosecutors said.

A jury deliberated for just two hours before returning their verdict, the report said.

Avril Lavigne 'Cried for Real' in Raw 'Wish You Were Here' Video

Avril lavigne  known around the globe for her musical chops and unapologetic bravado. But the Canadian songstress in recent years has expanded her resume by tapping into fashion with her own clothing lifestyle brand, a fragrance line (Wild Rose) and a foundation to help youth with disabilities and illnesses.

In an interview with Billboard.com, the multifaceted entertainer dished about her career, touring and how music has inspired her to branch out beyond the recording studio.

The superstar's fourth studio album, "Goodbye Lullaby," was released in March and continues to resonate with fans with songs such as "What The Hell" and "Smile." The most current single, "Wish You Were Here," showcases Lavigne's more vulnerable side.

"It's a song written about missing someone and looking back and remembering all the good times and all those awesome moments," Lavigne says. The song is "stripped down. It's kind of raw, but also emotional. I cry in the video and that was something that I did on purpose, but it was something that was real."

Lavigne, who made a cameo on Rihanna's music video "Cheers" earlier this year, next takes her Black Star Tour to her native country for 16 dates throughout October.

"I'm having the most fun I've ever had," says Lavigne about the upcoming leg of her tour. "Every night you have a different crowd. Some are more rowdy than others and you want to get their energy up and get them to have a good time."

When she isn't touring she spends her time supporting The Avril Lavigne Foundation through a partnership with Easter Seals to fund programs for children with disabilities. Her time is also spent creating everything from T-shirts to accessories for her clothing line Abbey Dawn which, she says, is always tied to the music she writes about.

"As I got older I really started appreciating fashion more because it's really a big part of what I do with my music career," Lavigne says. "I'm pretty much designing for myself and it's a rock 'n roll brand. It's another way for me to create."

Avril Lavigne: NYFW show will be great

Avril Lavigne insists this year's New York Fashion Week will be the best yet.

The 26-year-old Canadian songstress is famed for her mix of edgy punk and girly glam, and regularly wows with her rock aesthetic. Her love of fashion saw the launch of her own clothing line, Abbey Dawn, three years ago.

Avril is preparing to show her new collection at New York Fashion Week this month, and the stunning star is excited at the prospect.

"I've had my line for three years now, and I really feel like this is the best season yet," she told The Huffington Post.

"It takes a while to tweak stuff to where I want it to be, but this season is the best yet. I have footwear, swimwear, eyewear, accessories, women and men's collections. I've done Fashion Week before, but this year it's going to be even better."

Avril came up with the idea for a clothing line when she was 19-years-old. The singer says her music and fashion go hand-in-hand.

"After the release of my first album, I realised how much fashion was involved in my musical career," she explained.

"With a lot of the designs, I try to tie in some of my lyrics and more musical elements."

It was recently revealed that TV personality Kylie Jenner is set to make her New York Fashion Week debut on the Abbey Dawn runway on Monday.

The 13-year-old model-and-reality-TV-personality is famed for appearing on hit show Keeping Up With The Kardashians alongside half-sisters Kim, Kourtney and Khloé Kardashian and the rest of their family.

Kylie is said to have got the nod for the show thanks to her stepbrother, Brody Jenner, whose is Avril's boyfriend.

Kylie Jenner to Walk in Avril Lavigne’s Fashion Week Show

Looks like Kylie Jenner is about to follow in her big sisters’ stylish footsteps.

According to WWD, Kris and Bruce Jenner’s youngest child will make her runway debut during New York City Fashion Week Monday at the Abbey Dawn by Avril Lavigne show, where she will take three turns on the catwalk inside the Metropolitan Pavilion.

Sister Kendall may be the modeling maven of the family, but this isn’t the first time Kylie has stepped in front of the camera for fashion: the tween starred in a series of TV ads for Sears last year.

Considering the family connection to Lavigne — Kylie’s half-brother Brody Jenner is the designer’s current beau — we wouldn’t be surprised to see a few famous faces lining the front row come Monday, cheering for their favorite fashionista. Tell us: Are you excited to see Jenner walk the runway?

Avril lavigne to showcase her collection at NY fashion week

Abbey Dawn’s Spring 2012 collection will show at the Style-360 Metropolitan Pavilion, a venue where we’ve seen other displays of sartorial splendor by esteemed names in fashion such as Kim Kardashian for Bebe in 2010. Alas, Kim -- step-sister of Avril’s beau, Brody Jenner -- will not be participating in NYFW this season (at least as a designer).

In the meantime, Avril's press release promises "a high-energy runway fashion show." Can’t wait! Perhaps we’ll attend wearing one of the sk8ergirl’s designs (we hope this comes in our size).

Below, two Abbey Dawn original designs:

Paramore laugh off Lavigne comparisons

Paramore "laugh" about comparisons between them and Avril Lavigne.

The band's guitarist Taylor York said the group - fronted by Hayley Williams - used to put up a fight when people spoke about them in the same light as female singers, such as Kelly Clarkson, but now they just laugh off the comparisons.

He said: "Since we have a girl singer we get compared to Avril Lavigne and Kelly Clarkson. We'll always get compared to any girl-fronted band.

"We used to try to fight it and be like, 'No, we're different'. Now we just laugh about it because people are always going to compare us to people we don't think we sound like."

The 21-year-old musician says the group - which includes bassist Jeremy Davis, but who lost two members Josh and Zac Farro when in December 2010 - are currently in "a better place" than ever before.

He added to watchmojo.com: "We're in a better place than we've ever been. We're really fortunate to have come out where we are and just thankful that our fans have been supportive through that. We have no intentions of stopping."

In the video, Lavigne screams as the fan is caught and dragged offstage by her brotherMatt who is also her security guard.Avril Lavigne was attacked by a fan onstage on Tuesday night (August 2) during a concert in Brazil.

The singer was about to launch into a cover of Coldplay's 'Fix You' when a female fan climbed onstage and attempted to grab or perhaps embrace Lavigne, according to The Hollywood Reporter.

A video of the incident can be seen below.

Lavigne is heard saying, "It's all good" before carrying on with the show. The singer is set to appear at the Teen Choice Awards later in the week. She returns to the road in September for dates in Russia, Italy, the Netherlands, Belgium, France and Germany.

Adam Lambert and Avril Lavigne to Mentor Kids on 'Major and Minors'

Adam Lambert, Colbie Caillat, Avril Lavigne and Claude Kelly are joining the list of recording artists who will mentor the dozen youngsters competing on Hub TV's fall show "Majors and Minors." including Brandy, Leona Lewis, Jordin Sparks, Sean Kingston, Mike Posner and One Republic's Ryan Tedder have already committed to assist the budding performers, aged 10-16, on the series.

Taping began this week for the show, which will premiere Sept. 23 on the former Discovery Kids that has been rebranded as the Hub across television and Internet platforms. Hasbro is Discovery's partner in the channel.

"Majors & Minors" is the rare competition show in which no performers are voted off. After 15 weeks, a valedictorian will be determined and that individual will receive a recording deal with the RCA/Jive Label Group and an opportunity to be featured in a cross-country concert tour.

"It's not about the drama," executive producer Timothy Bogart said Friday at Discovery's Television Critics Association session. "We have found children who are artists already and we watch their journey."

Bogart's brother Evan, a songwriter and TV producer whose credits include co-writes on Rihanna's "SOS," Hot Chelle Rae's "Tonight Tonight" and Brandy's last Top 40 hit, "Right Here (Departed)," said the selected performers are all individuals their company, Boardwalk, wanted to work with. Without detailing what contractual holds they would have on the performers once the show is finished, he said, "our goal is to work with all of them but we may only work with a few of them."

Brandy joined the Bogarts and executive producer Gary A. Randall to explain the show to the writers assembled. She mentioned that she has already advised to the kids to "keep family around" as they venture into show business.

All of the onstage talent agreed "American idol" has played a significant role in making children want to achieve stardom at an increasingly younger age. "Its beautiful to see all of that passion about their talent," Brandy added.

The dozen aspiring singers and dancers - who will also learn how to write songs during the show -- opened the session with a medley of the Jackson 5's "ABC" and Jesus Jones' "Right Here, Right Now."

Avril Lavigne Goes Casual For Abbey Dawn Event

Now, here’s something we’d never expect to see Avril Lavigne wearing: sandals! The “What The Hell” songbird stepped out in Berlin today to promote her Abbey Dawn line at the Bread & Butter fashion trade show dressed in a casual off-the-shoulder shirt, star-printed pants and leather studded flip flops that looked more “South Beach” than “Germany”. We love your red toenails, but where are the usual Doc Martens, Avril?

Avril Lavigne Takes Abbey Dawn To Berlin

Stepping out to promote her clothing line, Avril Lavigne was spotted leaving Ritz Carlton Hotel in Berlin, Germany earlier today (July 6).

The 26-year-old pop/rock songstress kept it casual for her mid-week meetings, dressing in a black cut-off t-shirt, black leggings, and a pair of running shoes.

After what appears to be a super-successful workday, the fashion designer took to Twitter to reveal some exciting news, writing, "Great day at Bread and Butter in Berlin. Abbey Dawn signed new stores in Spain, Portugal, Ireland, France, Poland, Germany. So cool :) xo"

Lavigne, who is looking to expand her line to footwear and denim in the future, recently told press, "Our main goal right now is to make our clothes available to fans all over the world. When I see girls wearing Abbey Dawn, it's awesome."
