Zac Efron: Always the Diva

Remember when we shared with you Zac Efron's hair straightening adventure at Ashley Tisdale's birthday party? Well he's at it again!

The 20-year-old High School Musical star was so concerned about his hair backstage at the Teen Choice Awards on a hot and sticky Aug. 3, he asked to borrow a curling iron.

"One of the awards staff asked Zac who it was for, and he said [girlfriend] Vanessa Hudgens, but it was really for him!" says a source.

Moments later, Zac was seen styling his locks. "He said the humidity was killing his hair and that it was flat."
