Daniel Radcliffe works his magic with a mystery brunette ... but what will girlfriend Rosie Coker say?

Does this spell the end of Daniel Radcliffe's romance with long term girlfriend Rosie Coker?

The Harry Potter star was spotted arm-in-arm with a pretty girl during a night out in Chelsea last week.

He was snapped outside the Aztec Latin Lounge by himself, but later in the evening he was joined by the mystery brunette - who seemed more than happy to snuggle up the star.

Radcliffe later moved on to Raffles, a private members club on the King's Road. 

An onlooker told the Daily Star: 'She initially did everything she could not to be seen with Daniel but she probably realised there wasn’t much point in trying to hide. She then went to the other extreme and linked arms – making it look like they’re a couple. 

'Daniel looked really relaxed and happy with her – it was obvious they’d had a nice evening together.

Anyone who didn’t know he had a girlfriend might have thought it was a date.'

Radcliffe had dressed casually for the evening, wearing a baseball cap, jeans, a checked shirt and suit jacket.

He also hasn't appeared to have shaved for a few days, completing the dressed down look.

His companion however opted for a smarter look, wearing a petty dark top and black jeans. 

Radcliffe began dating production assistant Coker last summer, but it was also reported last month that their relationship has ended after he was spotted with another girl.

After Justin Bieber's beer revelations, his girlfriend Selena Gomez makes her own controversial move by posting gun picture on Facebook

She's a squeaky clean, Justin-Bieber-dating, Disney star who's BFFs with angelic Taylor Swift. But we knew Selena Gomez wasn't THAT sweet all the time - and she's proved us right. As she's posted a picture of herself shooting a gun at a firing range in Bulgaria.

"Releasing some stress" she wrote after uploading the picture to Facebook and Twitter. We always thought she was more of a "write it down in her pink sparkly diary" girl than "fire a massive gun" person ...

However, she was bought up in Texas, and if TV isn't lying to us, EVERYONE in Texas has a gun. Because Dallas was an actual documentary, right?

Selena's target practice took place in Bulgaria - she's there to film new movie The Getaway with Ethan Hawke.

Selena, 19, is playing a mysterious character - called "Kid" - and Ethan Hawke is a "burnt-out racing driver whose wife is kidnapped". It also stars Angelina Jolie's dad Jon Voight. We're not really sold yet, sorry Selena ...

The ‘Woman In Black’ star is set to leave the silver screen behind for his next role in a new TV drama alongside Jon Hamm.

Daniel said yes to the role as soon as he heard that the Mad Men star was also onboard.

"This is a great role for Daniel and he's pretty excited about the prospect of working with Jon." A source told the paper.
