Britney Spears danced along to her ‘Circus’ lead single ‘Womanizer’ on ITV’s ‘The X Factor’ on Saturday in London. The pop star had a different outfit that her Bambi awards and ‘Star Academy’ performances earlier in the week, and she also didn’t have the giant ball to climb on this time around. Again, Britney’s mic was non-functional. Afterwards, host Dermot O’Leary briefly spoke with Britney, who had no comments about the contestants prior performances but did wish them luck. Video of the dance performance at xfactor.itv.com has since been removed.
