Mr. Popular started the party off as he was called up on stage by DJ Vice. He started by giving out shout outs and then danced to the music with his close friends.
Kevin even called Brody Jenner on stage. When Brody made it up he announced on the mic that it had been a long time since Kevin Federline had been out. He hasn't been out because he's been playing daddy like he should! Nevertheless, judging by his face you could tell that he was really excited to be out of the house partying with pals. The "rapper" kept coming back on stage making shout outs and taking shots with his friends behind the DJ booth.
Britney's cousin Ali Simms was also at the bash. When Hollyscoop asked if she still speaks to Britney she said, "yes."
