Celebs, Hot Celebrities, Celebrity Pictures

Britney spears failed to attend Kevin Federline's album listening party on Friday. Insiders at the Las Vegas Review spotted the two arguing at Caesars Nero restaurant and Federline may or may not have been wearing a white tank top.

The review claims: "Kevin went on to perform two songs, America's Most Hated and Rockstar from his debut album Playing With Fire, after an introduction by Paris Hilton's mother Kathy. Federline entertained a few hundred fans, as well as celebrity friends, former Fresh Prince Of Bel Air actress Tatyana Ali and Kathy's husband Rick - but his superstar wife was nowhere to be seen."

I never know when some young punk is going to try and make a name for himself by lighting me up. Man, I have so much honor.
