Kevin parties in Vegas

Kevin Federline's second son with Britney Spears was born just three weeks ago, but already the aspiring rapper is back to his old bad-boy ways - leaving his wife and babies at home in Malibu to party up a storm in Las Vegas.

Just six months ago, Spears put a semi-permanent kibosh on K-Fed's unquenchable love for Vegas weekends with the guys. Britney his allowance and made him ask for permission for out-of-town trips. But with the birth of her second child, Sutton Pierce Federline, it seems that Spears' attention is distracted. Federline and a crew of his boys took a private jet to the Venetian hotel-casino Friday night for the weekend-long celebration of the one-year anniversary of the club Tao.

"He booked a table at Tao for both nights," said our source. "He was surrounded by women, was drinking a lot and dancing on the banquette. Every time one of the girls tried to take a picture, he freaked out and wouldn't let them." Federline wasn't the only one having a good time in Sin City.
