GIMME GIMME MO'

**** BLACKOUT, THE NEW ALBUM, INSTORES NOW ! ****

Britney has increased her partying recently by A LOT.

Brit went partying toWinston's in LA on Monday night with her pals Osama Lutfi and Alli Sims.

An insider at Winston's tells us that Brit Brit requested the DJ to play Gimme More and he did.

Also, we're told she kept going in and out of the bathroom. Probably to powder her nose.

AND, she changed outfits twice.

Spears and crew left the club around 2:00 A.M., after a long night of pAArtying.
