Christina Aguilera has opted for sci fi chic in her new video.

The belting beauty pulls on a blue wig and strikes several sexy poses against a digital background for her new single Keeps Gettin' Better.

Christina's quirky new look is going head to head with Britney's steamy sauna video and Beyonce's monochrome ballad.

All three artists plus Leona Lewis will be battling it out for the top spot on November 3.
