Britney Spears has sparked further reports her marriage to Kevin Federline is in trouble, after she failed to attend his album listening party on Friday. (maybe she knew how bad it would be)!!!


The couple and their seven-month-old son arrived in Las Vegas, Nevada, last week, ahead of wannabe rapper Federline's gig at the Pure nightclub at the Caesar's Palace.


Local newspaper the Las Vegas Review Journal reports the couple were spotted arguing in Caesar's Nero restaurant ahead of Federline's show and Spears retired to their hotel suite in tears.


Federline went on to perform two songs, America's Most Hated and Rockstar from his debut album Playing with Fire, after an introduction by Kathy Hilton. Federline entertained a few hundred fans, as well as celebrity friends(!!!!).


Well Kathy and Rick Hilton where there are they classed as celebs?? But his superstar wife was nowhere to be seen.


Come on Britney, do us all a favour, get rid of him so he goes back down into celeb z-list land and then we wont have to see him anymore!!
