Federline lives it up while Britney faces judge

As Britney Spears faced the judge in her children's custody hearing, her ex-husband Kevin Federline spent time shooting scenes for episode seven of his guest spot on "One Tree Hill". After the shoot, Federline partied at a club like a rock star in the VIP area, ordering up rounds. When the club's deejay spun his ex-wife's new song, all eyes darted to Federline, clad in a white T-shirt and jeans and wearing noticeable bling. "When 'Gimme More' came on, I looked at him, and he didn't have any reaction. He wasn't dancing," said a reveller at the club. One observer said the VIP area is normally very quiet, "but when K-Fed is there, he brings the whole posse." As for how Federline enjoyed himself, she said: "He seemed happy. He seemed like he was having fun - he wasn't upset."
