Zac Efron Tips Vanessa Hudgens During 'Rent' Dance

Last night, Zac Efron presented a surfboard to Sandra Bullock for Choice Movie Actress for a Drama.

The 22-year-old actor then rushed to the Hollywood Bowl to once again support his girlfriend Vanessa Hudgens as she played Mimi, a junkie stripper, during another performance of the hit musical Rent.

During the musical number “Out Tonight”, Zac got up from his seat and tipped Vanessa a few bucks during her sultry dance. How much did the big boy tip his leading lady?

“$20 bucks!!!” an inside source exclusively tells JustJared.com.

One JJ reader jokes, “Yet he spends $2,000 at a strip club… Vanessa got ripped off!” Haha, hilarious!
