Britney Spears‘s official website at BritneySpears.com has been updated with new insider photos from a dance routine rehearsal that Brit held this past Friday night. Britney and her cast of dancers appeared to be working on a routine possibly for a live performance of her new single Womanizer or maybe even a new music video altogether. Here are a few pics of Britney, one with whip in hand, at Friday night’s rehearsal:

Friday night Britney had dance rehearsal to work on a new routine. Britney, her choreographer Andre, and her dance crew had a blast playing around with some new moves. If you look closely, you’ll see that Britney is indeed holding a whip! Looks like her new music video might be even hotter than “Womanizer!”

I would LOVE it if Britney were actually working on her next music video already but something tells me that this routine might really be for an upcoming live performance. There was much speculation that Britney was gonna perform at the 2008 MTV VMAs in September but that didn’t happen. We’ve since learned that Britney may be appearing at the 2008 MTV Europe Music Awards which will be held in Liverpool, England on November 8. Naturally, there is new speculation that if she appears then she might also perform that night. Britney has also been confirmed to appear on X-Factor (the British American Idol) later on this year so she might be rehearsing for that. Personally, I don’t care what she’s rehearsing for … I’m just glad to see her hard at work. She’s been lookin’ real good for some time now … this is just another sign that she is back on the comeback track! Woot!
