Britney Spears is raunchy office girl and waitress in new video

Britney Spears has revamped herself with three explosive new images in her next video.

The star sizzles as a saucy secretary in a black bobbed wig, low-cut top and Fifties spectacles and as a raunchy leather-clad waitress with heavy eye-liner and magenta hair.

She is even seen in a negligée revealing a black bra, with her familiar tousled blonde locks, wagging her finger cheekily.

The shots, from the forthcoming Womanizer video, show Britney's months of working out have paid off.

The images were leaked online today ahead of the official launch on Friday.

The single itself was also leaked two weeks ago.

But the video, if these pictures are anything to go by, is set to give Spears, 26, the comeback she has been hoping for.
