After nine nights of hard partying (with brief intervals thrown in for rest, relaxation, lingerie buying and multiple CVS runs), Britney Spears, 24, was at it again last night — this time in pants and with her back-up dancers in tow. 

Britney and her crew hit Club Area in LA, and were seated right next to her new secret BFF for life, Paris Hilton, her publicist, Elliot Mintz, sometimes boyfriend Stavros Niarchos and greasy oil heir, Brandon Davis. Apparently the tipsy pop star failed to acknowledge her new friends quickly enough, so Paris made it a point to stop by and say hello. The dynamic duo were later spotted sitting on a sofa holding hands while they whispered and giggled.

Meanwhile, Brit’s ex-boyfriend, Justin Timberlake resisted the urge to hold another dance-off when he and his party of back-up dancers arrived and were seated a few yards away from Britney. While the newly-single star got her drink on, Justin hit the dance floor where he surrounded himself with his entire crew — that just happened to include several of Kevin Federline’s friends.

After closing down the joint, Britney’s boys (including So You Think You Can Dance judge and former Spears choreographer, Brian Freidman) escorted her out and to a nearby Jack in the Box restaurant where they picked up some grub before heading off to a friend’s house in the Valley.
