New York, Aug 21 (IANS) Finally it is out - "Harry Potter" star Daniel Radcliffe's girfriend's name is Rosanne Coker and her dad has confirmed that the two are dating.

The 22-year-old revealed last month that he had been secretly dating, but refused to name the woman he was "very much in love with". However, Radcliffe has since been sported holding hands with his mystery partner in New York, where he's currently starring in Broadway musical "How to Succeed in Business Without Really Trying", and she's been identified as production assistant Rosanne Coker.

"I don't want to say too much really as they would really prefer to keep things quiet. But Rosanne has worked on the last three 'Harry Potter' films, so she and Daniel have known each other quite a long time. They have been going out for just over a year now," dailystar.co.uk quoted Coker's dad, Malcolm, as saying.

"I have met Daniel and he is a lovely guy. I'm just really happy for Rosanne and as long as she is happy that is all that matters to me. No other parent would ask any more. I know it's not a normal life they live. But they have a lot of fun together and, at their age, what more could you ask? Who knows where it is going to lead?"
