Kevin Federline said bye bye to Britney Spears and his boys this weekend for some Vegas fun with new girlfriend Victoria Prince.

The wannabe rapper escaped the ongoing legal talks taking place about his boys joining their mother on tour next month, in favour of a stop off in Sin City with Volleyball player Victoria.

"He showed up to Tao with about 10 friends for dinner," an onlooker tells OK!.

"Then they all headed into the club and sat at a corner table on the dancefloor near DJ Vice."

According to sources this is K-Fed's second visit to Las Vegas in a week, reigniting rumours that Brit's ex-husband could be revisiting his former lifestyle.

The notorious party boy allegedly left behind his wild ways last year when he was granted full custody of sons Jayden James and Sean Preston.
