Daniel Radcliffe is "not sure" he can stop himself sleeping with dancers when he performs on Broadway.

The 21-year-old actor - who is to appear in New York-based musical 'How to Succeed in Business Without Really Trying' from March 2011 - doesn't want to get romantically involved with anyone in the foreseeable future, but admits he is unlikely to stick to his plan.

He told Dazed and Confused magazine: "I've been in relationships from the age of 14 and now I'm single.

"I said to a friend the other day, 'Dude, I'm doing a show with dancers. I've got to be single.'

"He was like, 'Don't sleep with anyone in your show. That's a mistake.' It's good advice. But I'm not sure I'll stick to it."

Daniel - who previously dated actress Laura O'Toole - recently revealed he struggles to find dates with Women he hasn't worked with.

He said: "I was in a relationship for about three years. At the moment, I'm just being single and running around chasing girls. I'm not getting too many responses, but, yes, I'm having a go.

"I'm also starting to go on dates for the first time. I've never really done it because all my girlfriends I've met through work. So we got to know each other really well at work then kind of ended up going out."
