See, Kevin still knows how to party. He threw himself a party at Pure. He probably deserves it after becoming the responsible one in the Britney/Kevin realm of being. Was Kevin trying to cause a stir when he ended up partying with Shar Jackson that evening?

The Fed-Ex turned 29, and, according to People, spent his b-day dinner on Saturday “talking on the phone and texting the whole time,” though no word to whom. Then, he partied at Caesars’ Pure Nightclub with a special guest, first wife Shar Jackson. K-Fed’s parents hung out with Shar while Federline drank Jack Daniels and sang along to the music, such as it was.
