9 Shocking Teen Star Meltdowns

Leaping into the public eye as the golden boy of the High School Musical franchise, starring in the films and singing on their blockbuster soundtracks, Zac Efron and his girlfriend and co-star Vanessa Hudgens became celebrities overnight. Their image was never squeaky clean — when nude photos of Hudgens leaked on the Internet, Efron was the presumed recipient. But it was still shocking in September 2013 when Efron went through two stints in rehab for alcoholism and allegedly cocaine addiction. More recently, Efron was sidelined by a less controversial issue, breaking his jaw after slipping in a puddle and falling. But he’s gone on promoting his latest film, That Awkward Moment, fielding questions about rehab even with his jaw wired shut.
