Jessica Shakes It at Factory

A camera or two found their way into Jessica Simpson's surprise Friday night performance at West Hollywood nightclub Factory. The gay & lesbian club was filled with sweaty, dancing fans and Jessica didn't disappoint.

Not only did she deliver her latest hit "A Public Affair," but she also wowed the crowd with the old 80s Dead or Alive hit "You Spin Me Round (Like a Record)".

Simpson was joined on stage by some male dancers, prompting her to say: "I know, I know. The boys are cuter than me..."

Interestingly enough, Factory usually keeps it for the ladies who like ladies Friday night, with the aptly titled "Girl Bar." But, lucky for Jessica, this Friday night, the guys showed up too.
