Daniel Radcliffe Giggles Through First Love Scene

sure is doing his utmost to break free of his Harry Potter image. From baring it all onstage in the London (and soon, Broadway) play Equus, to filming a rather intimate love scene in his new film December Boys, the 18-year-old is making it clear that he's not just a kid.

But that didn't stop Daniel from getting a case of the giggles on the December Boys set when it came time to film the sexy scene with sultry actress Teresa Palmer. "It's very, very hard to stop giggling," the actor confessed recently about the scene, which was filmed when he was a lad of only 16. "I suppose the thing I was worried about was, 'Am I going to get an erection? Is this going to be really sexy? Is this going to be a bit awkward?'"

In the end, the young star, who says that co-star Teresa guided him through the scene, admits that filming steamy scenes isn't as enticing a job as it sounds. "When you get in there, it's not sexy in the slightest."
