Kristen Stewart at 'Camp X Ray' Sundance Premiere

Kristen Stewart braids it up for the premiere of Camp X-Ray during the 2014 Sundance Film Festival held at Eccles Center Theatre on Friday afternoon (January 17) in Park City, Utah.

The 23-year-old actress joined her co-stars Lane Garrison and Payman Maadi, and director/screenwriter Peter Sattler earlier in the day at the Getty Images Portrait Studio at the Village At The Lift.

Camp X-Ray‘s official summary: A young woman joins the military to be part of something bigger than herself and her small-town roots. Instead, she ends up as a new guard at Guantanamo Bay, where her mission is far from black and white. Surrounded by hostile jihadists and aggressive squadmates, she strikes up an unusual friendship with one of the detainees. As two people on opposite sides of a war, they struggle to find their way through the ethical quagmire of Guantanamo Bay. In the process, they form an unlikely bond that changes them both.

Robert Pattinson "all smiles" at Cosmopolis premiere

Robert Pattinson was "all smiles" at the Cosmopolis premiere after party on Monday (August 13).

The 26-year-old actor - whose girlfriend Kristen Stewart admitted to an affair with Rupert Sanders last month - appeared to have put his recent problems behind him when he arrived at the PH-D Rooftop Lounge at Manhattan's Dream Downtown hotel at around 10 pm, with onlookers describing him as "relaxed and comfortable" at the bash, despite the attention he attracted.

A source told People: "He was very charismatic, all smiles, looking very relaxed and hugging all who stopped by to say hi. The general crowd gravitated towards his table, but he was shielded by security. He was surrounded by women and the movie's cast."

"The whole room was watching him, and he looked genuinely at ease and comfortable the whole time." The evening capped off the first time Robert has appeared in public since the news of Kristen's affair broke, walking the red carpet at the New York movie premiere having earlier taped an episode of The Daily Show.

At the Cosmopolis screening, the Twilight Saga star admitted he felt "absolute terror" about getting close to his fans following his personal problems.

He said: "I felt fear, absolute terror. It's great - I didn't expect it from the first Twilight movie, I never expected my life to be like this and so it's kind of weird to have lasted. And for people to come to movies that I'm really like proud of and I didn't really think anyone's going to see, I mean it's like, it's kind of amazing."

Robert Pattinson poses nude in 13-hour photoshoot

In a photoshoot for French magazine 'Premiere' Robert Pattinson can be seen lying naked on the mattress with just a red silk blanket covering his modesty as he gazes at the heavily pregnant female.

The bed is scattered with videotapes and the British actor looks pale and tired as he stares at the dark-haired female.

The unique shoot is said to have lasted 13 hours and was an idea of the 25-year-old actor who wanted to dedicate it to director David Cronenberg's movies.

The images are apparently a homage to his respect for the filmmaker, who by casting him in Cosmopolis, offered him not only a passport following the success of 'Twilight' but also the opportunity to come and celebrate his entry to the adult age, on the steps of Cannes on May 25.

"Filming Cosmopolis with Cronenberg changed something in me. It gave me balls," the Daily Mail quoted him as telling the magazine about his latest role.

In the upcoming drama, which is based on the novel of the same name by Don DeLillo, Pattinson portrays billionaire Eric Packer who goes on a trek across Manhattan to get a haircut.

The actor - who is best known for his role as vampire Edward Cullen - clearly has a lot of respect for Cronenberg and is grateful for the opportunity.

"I'd never worked with a screenwriter who was this confident in his abilities,' Pattinson added. 'If he was stuck on a way to film a scene, he did something else. He knew the script by heart so he could afford it. It's kind of unnerving at first, but since I'm in every scene I memorised the whole script, like a play," he said.

However, Cronenberg is said to have admitted that Pattinson was stressing out about filming Cosmopolis, and he decided to shed some light on why.

"I'm going through a phase were I'm trying to determine what I can accomplish or not as an actor," Pattinson said.

"It's even more complex when you know you have a past, even though people like David don't pay any attention to it," he said.

With the release of Breaking Dawn: Part Two this November, Pattinson will finally be kissing his Twilight day's goodbye and is curious as to how the hysteria may change.

"I'm going to be 26 and I can tell you that it's starting to freak me out that I'm appealing to girls that are 13-years-ol," he said.

"I'm often wondering how things will change now, but I can't believe there's still one more to come," he added. 

Justin Bieber Premieres 'Mistletoe' Single: Listen

As the most wonderful time of the year approaches, the most wonderful teen pop/R&B superstar, Justin Bieber, has gotten fans in the Christmas spirit by unveiling "Mistletoe," the first single from his forthcoming holiday album, "Under The Mistletoe." The Biebs stopped by "On Air with Ryan Seacrest" on Monday morning (Oct. 17) to premiere the warm and fuzzy track.

The comparisons between "Mistletoe" and Jason Mraz's "I'm Yours," which began to surface after Bieber performed the track at a Buenos Aires concert last week, are even more apparent in the recorded version of the track: a simple melody dances around an acoustic strum and muted percussion as the pop singer turns on the romantic charm. "Kiss me underneath the mistletoe, show me baby that you love me so," Bieber coos to his "shorty" on the track.

After premiering the track, Bieber told Seacrest that he was excited for the release of "Under The Mistletoe," which arrives Nov. 1 through RBMG/Island Def Jam Music Group.

"Even though it's a Christmas album, it's probably my best album yet," says Bieber of the album, which feature Boyz II Men, Usher, the Band Perry and Mariah Carey, among other artists. "I got a lot of different genres on there, so I think it works for everybody."

The music video for "Mistletoe" will premiere on MTV on Tuesday night at 7:54 pm EST. Bieber teased the official clip by releasing a 30-second snippet last Thursday.

Bieber also revealed that he will join Seacrest in New York's Times Square for "Dick Clark's New Year's Rockin' Eve" on Dec. 31. The pop star will join previously announced performers Lady Gaga and Pitbull at this year's festivities.
