Zac Efron Sneaks Into His Own Birthday Party
But that could be almost anybody creeping in behind his girlfriend Vanessa Hudgens.
Not that anyone expected any kind of angsty rock-star public spectacle bender. Zac's a clean post-teen.
Guests at the not getting nude on Broadway Zac's party included girlfriend Vanessa Hudgens (who helped in the planning), High School Musical co-stars Ashley Tisdale and Monique Coleman, Brittany Snow, Michelle Trachtenberg and Amanda Bynes.
Bottles of liquor were rumored to be among some of the gifts given, and the after party was held at a nearby hotel.
So there is hope that Zac did do a couple of shots and throw up on the rug after all. Happy 21st, Efron!
