Chunky Britney Works Out For Ten Minutes

Britney went to Bally Fitness yesterday, but only worked out for a total of ten minutes. Later, the chunky "poptart" headed out for a night on the town – attending fashion designer Christian Audigier's birthday party at the Petersen Automotive Museum. While there, Brit lounged on a white sofa with a few friends and her dad, watching the festivities which included an impromptu performance by Fergie-lishus and an appearance by deformed freak, Michael Jackson.
