Zac Efron: The New American Heart Throb

The poster boy of the tweenybopper set is Efron -- one Web site even insists that one of every three teenage girls in America actually has a poster of him. Efron also happens to be Disney's most reluctant star. Though every breakout star in the cast of High School Musical has signed a solo record contract, he has turned all offers down. Though High School Musical may film dozens of sequels, he said he'd "hopefully not" do many more. And when High School Musical's cast went on tour, he was the only one who sat it out.

"If I had to hear the High School Musical songs anymore," he confesses, "I probably would have jumped off something very tall."

It's not that Efron isn't grateful. He knows that High School Musical transformed him from television-drama walk-in to leading man. That's why he's starring in the sure-to-be-a-hit sequel, which premieres on Disney on August 17th, in which the East High kids go to a summer country club and a Disneyfied class war ensues. However, Efron now has the clout to play by his own rules, so he fought Disney -- and won -- in order to be allowed to sing on the movie and album this time around.

"I didn't even sing on the first album," he admits. "It wasn't my voice in the movie. Even though I wanted to do it."
