Britney Auditioning for a New K-Fed?

Britney was looking hot and sexy in a menswear inspired hat and vest outside of the Millenium Dance Studio yesterday, where she audtioned hundreds of male backup dancers. We're not sure if it was for another tour or a new video, but we do know that Brit has a history of hooking up with the guys she works with (Justin, Matt) as well as backup dancers...was there a new K-Fed in the bunch?
