The breakup of "High School Musical" stars Zac Efron and Vanessa Hudgens was one of little drama (they reportedly ended things during a phone conversation), but there's still speculation over why the two split, since they were seemingly getting along just fine.
"They didn't break up and get back together like a lot of couples. They rarely even fought," a source told Us Weekly. Among the theories: the relationship ran its course, and Efron also wanted to shed his "High School Musical" image, which included Hudgens.
"He wants to put his whole "High School Musical" past behind him and be known as a sexy solo actor like Leonardo DiCaprio," one Efron source told the magazine. "He was ready to experience life as a single man."
