Happy birthday, Zac Efron!
My, how you've grown... The actor, who turns 31 on Thursday, sure has come a long way since he rose to fame with his starring role in the 2006 Disney Original Movie High School Musical. His portrayal of student, basketball star and your imaginary boyfriend Troy Bolton captured millions of hearts and turned him into one of the most sought-after actors in Hollywood.
And if we're about to get all nostalgic on you, can you believe High School Musical 3: Senior Year, the last movie starring the original cast and the first to be released in theaters, will celebrate its 10th anniversary on October 24?
