Vanessa Hudgens made her first public appearance since splitting with Zac Efron last night -- for her 22nd birthday party in Las Vegas!
Hudgens, looking sexy in a short, silver Pleasure Doing Business dress, partied at PURE at Caesars Palace with friends Brittany Snow and Ashley Tisdale.
Though she and Zac split, Hudgens tells UsMagazine "we're good."
