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 soon he was joined by the mystery brunette - who seemed more than happy to snuggle up the star.

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

'Daniel looked really relaxed and happy with her it was obvious theyd had a nice evening together.Anyone who didnt 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.

An insider told the newspaper: 'For someone with a girlfriend Daniel does spend a lot of time with other girls. They could be just friends but its been two in less than a month so fans are going to start thinking hes definitely split from Rosie.'

Earlier this year, Radcliffe spoke about marriage: saying: 'Rosies lovely. Shes a wonderful, wonderful girl whos far too good for me.

'When growing up, I thought of marriage as being very official, drawing up a contract. It seemed slightl! y clinical! to me. But then you meet somebody that you really love and you think "actually, I wouldnt mind standing up in front of my friends and family and telling them how much I love you and that I want to be with you forever"'.
