Britney Works Up A Sweat!

She's really committed, y'all! After a busy weekend of gym and vocal workouts, our girl Brit again hit up the Bally's in Culver City for another day of exercising... and later she heated things up in the Ritz Carlton sauna! Don't ya wish your girlfriend was hot like Brit? If she does have another album in the works, think it'll be better than Blackout?
