The Charlie St. Cloud star turns 23 today -- October 18th! We hope he'll find time celebrate even though he is busy filming The Lucky One, a drama to be released in 2012.
Happy 23rd birthday to Zac Efron!
- Zac is a huge baseball fan. His most prized possession is is autographed baseball collection.
- Zac was super ambitious at school and he used to get angry at himself when he got a "B" instead of an "A" in his classes.
- As a teen, Zac had a crush on Tyra Banks. "When I was younger I used to lie on my bed and look up at a poster of Tyra Banks on my ceiling," he says. "I thought she was the most gorgeous thing in the world."
