Vanessa Hudgens wore a furry fox hat on her way from LA to Las Vegas to celebrate her 22nd birthday on Saturday. She sported a tight minidress for her special dinner at Social House, and her bash at Pure lasted late into the night. Her close friends Ashley Tisdale and Brittany Snow were there to party with Vanessa, though noticeably absent from the girls' night out was ex-boyfriend Zac Efron. Most of you weren't surprised by their recent split, and Vanessa maintains her current relationship with Zac is "good." Single Vanessa may not have much time for dating in 2011as she preps for the upcoming releases of Sucker Punch, Beastly and Journey 2: The Mysterious Island.
