At least someone is getting the chance to spend Britney's money. Ex-hubby, Kevin Federline, spent his 30th birthday in Las Vegas at Pure Nightclub on Friday.

He partied it up at a VIP table with about 20 of his friends including his attorney, Mark Vincent Kaplan, and with is ex-girlfriend/baby momma, Shar Jackson. The Pussycat Dolls even sang him a very sexy version of "Happy Birthday."
