Hey Bristol Palin, we've found you a drinking partner.
On the same day that this formerly impregnated celebrity turns 21, Zac Efron also celebrates a birthday: the young stud is now 24. He's eagerly awaiting your best wishes.
Efron has enjoyed a quiet, drama-free 2011. He split with Vanessa Hudgens near the end of last year, and gossip site have linked him with both Teresa Palmer and some other dude over the last few months. But that's been about it for Zac.
He'll next be seen in December's New Year's Eve.
Other stars celebrating birthdays today include: Freida Pinto (27), Ne-Yo (28), Jean-Claude Van Damme (51) and Mike Ditka (72).
