Britney Spears posted a new promo for The X Factor on Twitter today, and we can't WAIT for the show to hit the small screen on September 12! Not only does Brit look amazing in the brief clip, but we also get to see her sassy side ... check out the video above!

In other Brit Brit news, it's being reported that the 30-year-old pop star may be doing a surprise appearance at the 2012 MTV Video Music Awards next weekend. We're guessing Brit's X Factor boss Simon Cowell is pushing for that!
