Zac Efron Shakes His Santa Booty

Zac Efron drops by The Tonight Show with Jay Leno on Wedneday to hype up the upcoming release of High School Musical 3: Senior Year.

The almost-21-year-old turned candy cane red when Leno played a blast-from-the-past clip of Zac. The home video showed a 9-year-old Zac singing and shaking his booty during a kids’ play. Hearing it came from girlfriend Vanessa Hudgens, who was on the show last week, Zac joked, “I’m gonna call Vanessa after this.” Somebody’s in trouble tonight! Watch the video below!
