Kevin Federline

Well his 31st b-day isn't until tomorrow, but it looks like he's getting his party on a day or two early!

Last night Kevin Federline celebrated at Brother Jimmy’s in Murray Hill, New York, and he was joined by girlfriend Victoria Prince, his father Mike, Taye Diggs and Kourtney Kardashian. Random much?!

According to NY Daily News, the group ate hot wings, slurped down shots of Patron and fishbowls of Swamp Water, which is a bunch of alcohol and juice served in a fishbowl with multiple straws. Sounds uh, super yummy.

After dinner, the group headed to Greenhouse, where K-Fed and Victoria were spotted “dancing very provocatively...They were kissing and touching each other excessively,” said one eyewitness.

Glad he had a good time...so when is he going to get back to work? And working out?
