Kevin Federline, showing that he is a more fi-to-be- parent than ex-wife Britney Spears, tore up Las Vegas over the weekend.  He was dancing, grinding, and drinking more drink than Danny Bonaduce.

The Fed-Ex, reports People, partied like a Brit-Brit at Tao, and had plenty of liquid refreshment around him — and no shortage of female entertainment. “He was grinding up on a few of the girls,” says a mag source. “He had a flashlight and was shining it on some of the girls around him.” What’s more, ever the class act, Kev held up a cigarette lighter when the DJ spun Jay-Z’s “Big Pimpin’.”

Hopefully the judge will just give the kids to Britney’s mom, Lynne.   Maybe we shouldn’t be so hard on K-Fed.  I mean what’s a single dad of 56 children to do?
