Russell T. Davies, writer of the series has targeted the pop princess as a desirable guest star to feature in the next series of the science fiction show. As befitting Spears` star status, the American gal, who recently split up with hubby Kevin Federline, would not just play a single character.

Instead she would play a whole race of sex-loving alien clones on the show, which stars David Tennant as Doctor Who and Freema Agyeman as his new assistant.

"I`d love Britney to do it – it would be so much fun," Davies was quoted by Contactmusic, as saying.

If Britney accepts she would join a long list of celebrities who have previously appeared on the show, including Courtney Pine, Andrew Marr and Derek Acorah.

However budget difficulties, as well as Spears` willingness, could stand in the way of Davies and his sex-mad Britney clone dream.

"I`m not sure if she`ll come to Cardiff where the show is shot so I`m nagging the BBC to fund a Hollywood special," he added.
