GOSSIP: Vanessa Hudgens…Back in the Game

If Vanessa Hudgens is upset about her split from Zac Efron, she did a good job of acting just fine about it as she celebrated her 22nd birthday in Las Vegas Saturday night. Accompanied by a gaggle of girlfriends, including Brittany Snow and Ashley Tisdale, Vanessa was all smiles and sexy in a skintight silver dress. But when asked about Zac specifically on the red carpet at Pure nightclub, Vanessa said… TWITTER: Follow PartyGirl “We’re good,” giving reporters the thumbs-up. Guess they really have remained friends. Inside the club at Caesar’s Palace, the birthday girl recieved a three-foot-tall red velvet cake before drawing the curtains at her VIP table for privacy. “The girls were taking shots, drinking champagne, cocktails and Red Bull,” a source says. “Vanessa took off her shoes, jumped on top of the furntiure and had a dance off with Ashley!” According to an onlooker, she did take a breather when Mario’s “Break Up” came on, but quickly got back up when the deejay played Jay-Z’s “On to the Next One.” So clearly, Vanessa doesn’t want to celebrate her split from Zac after five years of dating, but she’s ready to move on to a new guy.
