K-Fed Solo in Sin City

Kevin Federline was blinged out when cameras spotted him in Las Vegas this weekend, but one accessory was notably missing -- his wife.

Though Britney Spears gave birth to the couple's second child together less than a month ago, Federline appeared to be enjoying the time away from the full house, stopping at the trendy TAO nightclub/restaurant for dinner.

It appears Britney has little to worry about though -- K-Fed was noticeably solo.
