Kevin Federline Celebrates 29th With Shar

Turning 29 is a pretty big deal. It’s the last year before you’re officially old. For Kevin Federline it was an even bigger deal, being that his divorce from Britney Spears is final and he is a free man.

K-Fed celebrated the big 2-9 in Las Vegas this past weekend. In attendance were his parents, kids, and ex-girlfriend Shar Jackson. The party took place at Caesars Palace, most notably the club Pure.

After checking into Caesars Palace, Federline spent the remainder of the afternoon relaxing in a VIP cabana at Caesars’ Venus Pool Club, a private somewhat hidden topless pool adjacent to the general public pool, a source tells People magazine.

The birthday festivities kicked off Saturday night, with Federline (who turned 29 on March 21) starting his evening at Social House, dining on Asian fare with 14 of his closest friends and family by his side, a source tells PEOPLE. “He was talking on the phone and texting the whole time,” said the source. Later, Federline made his way to Caesars’ Pure Nightclub, where his ex Shar Jackson was already present.

After a night of drinking Jack Daniels and making random announcements over the house microphone, K-Fed retired to the “Rainman” suite. Must be nice.
