High School Musical 3: Senior Year comes out Oct. 24, and it's only a matter of time before Vanessa Hudgens and Zac Efron become the next Joanie and Chachi.

The blond-haired, baby-faced actor had a string of minor hits such as The NeverEnding Story II, Ladybugs (with Rodney Dangerfield), and the futuristic television show SeaQuest DSV, but his regular appearances in teen magazines cemented his status as a junior high locker pinup from 1989 to 1996. Eat it, Scott Baio.
