Britney Spears is set to showcase her ranchiest routine to date when she performs on U.K. talent show The X-Factor later this month.

The Toxic hitmaker is set to thrill fans with her new single Womanizer on the hit TV talent contest after music mogul Simon Cowell persuaded her to appear on the series following her triumphant comeback at the MTV VMA awards in Los Angeles in September.

Spears has teamed up with her original choreographer Brian Friedman - who also plans the X-Factor contestant's weekly dance routines.

And the dance guru promises Spears' set will be a steamy affair.

He says, "Britney is at her raunchy best. She's back on top of her game."
