No word if she'll wear more than a glitter bra and panty set.

You've seen the VMA commercials with wacky British comedian Russell Brand. Everyone here has made comments about the one with Britney Spears, which has us all curious if Britney is performing.

All sources say no, Britney is not performing. But we're never so easily convinced, especially when we're referencing Perez. New footage has just been released of Miss Brit rehearsing a new song and, from the looks of it, both her body and voice are in good form.

Is she really going to try this again? If she performs at her pre-K-Fed level, she might give her career a boost, and make up for last year's chubby/drunk/lip synched disaster.

We're tuning in to see the whole show, and have a good chuckle at Russel Brand (ugly sexy!), but you betcha the volume is going up if Britney takes the stage.
