Britney is Keepin it Classy

So much for Britney's pledge to clean up her act. The newly single pop star continued her hard-partying trampage Sunday night at a Los Angeles burlesque club 40 Deuce, when she jumped onstage between striptease acts.

Britney and some girlfriends gyrated for the crowd, with Spears, cigarette in hand, unzipping her top and baring her bra.

She was having so much fun, the club's manager had to step in and remove her from the stage. But the singer wasn't having it. She quickly jumped back onstage, forcing the manager to dislodge her once again so that the real dancers could finish their show.

Spears returned to the bar, where she refreshed herself with a cocktail of champagne mixed with Coca-Cola. Keepin' it classy, Brit. Keepin' it classy.
