Actor Daniel Radcliffe has discovered that his co-star Emma Watson is a "vigorous" kisser after locking lips with her in "Harry Potter And The Deathly Hallow".

"I was ambushed by that! That was incredible, I was not expecting that. I always thought it was going to be this soft, sensual sort of moment and suddenly there was this vigorous kissing happening to me," thesun.co.uk quoted him as saying.

"She is a bit of an animal, she is, she was great. But then I'm not complaining, there are tens of thousands of men that would cut off limbs to be in that position," he said.
