Wizard and muggle world unite -- it's time to celebrate Daniel Radcliffe's 20th birthday today!

We've watched him grow from a tiny little tyke in Harry Potter and the Sorcerer's Stone when he was just 11 years old into a certified hottie in the uber successful Harry Potter and the Half-Blood Prince that came out last week and has already shattered its own records to be the highest grossing HP movie to date ($159.7 million in the first five days -- whoa!).

Join us in congratulating Dan on an amazing week at the box office... and a super special birthday today!

Fun facts about Dan:
- What does Dan think of the early Harry Potter films? "For me to look back on the old films is an almost entirely destructive thing to do. I just torture myself over it. I mean, I was young. I can't be held accountable for the performance I gave in the first two films: I was 11 and 12. I wasn't like Dakota Fanning ... who could seemingly just do it. It was very much a child's performance." Awww... so modest!
- He has two dogs, Binka and Nugget.
- Dan's ideal of a perfect girl? "To be honest, just somebody who makes me laugh, intelligent a bit. I like somebody who's slightly mad, slightly eccentric."
