Vanessa Hudgens is refusing to dwell on her reported split from Zac Efron - she's celebrating her birthday with a lavish nightclub party in Las Vegas.
The actress, who turned 22 years old on Tuesday (14Dec10), is alleged to have recently parted ways from her High School Musical co-star after the relationship "ran its course".
A source told EOnline, "It's nothing dramatic. There's no third party involved. They were together for so long."
But Hudgens isn't letting the split ruin her birthday plans - she's heading to Sin City's Pure Nightclub on Saturday (18Dec10) to mark her big day with an extravagant bash.
