K-Fed Celebrates Birthday with Victoria Prince, Kardashians

As we talked about over the weekend, Kevin Federline wasn't able to make it to Vegas to celebrate his 31st birthday due to family commitments. Dude is banking $5,000 per week just to watch his own kids while Britney Spears tours.

That's the life if you can get it.

It's good to see, though, that he did sneak away with girlfriend Victoria Prince for some partying at M2 Ultra Lounge in New York's Meatpacking district ...

Hurrying to his private table in the back, Federline spent most of the night dancing and kissing Prince, always keeping her within his reach. Hot stuff.

He also partied with some of the Kardashian sisters - sorry, no Kim Kardashian pics, she wasn't around - and a birthday cake glittering with sparklers.
