Blighty's own Posh Spice is to follow in the footsteps of new best mate Eva Longoria by performing live with saucy girl group the Pussycat Dolls.

Heat magazine reports that David's wife will join the troupe for a one-off stint at Las Vegas gambling heaven Caesar's Palace.

"Victoria's been in talks with the Dolls for some time and will be joining them onstage," confirmed Alisa Boushey, a spokesperson for the band.

"She would have done it sooner but it's been a question of her busy schedule. But it will be happening very soon," she added.

Other starlets to join the LA-based girl band so far - aside from Desperate Housewife Eva - include big-screen thesp Scarlett Johansson (she of the fabulous breasts, according to gal pal Natalie Portman) and sex-mad socialite Paris Hilton.

Writhing with the Dolls on stage is not likely to have been a stretch for wannabe porn-star Paris, who notoriously performed a whole other kind of dance with the unsavoury Rick Salomon in straight-to-DVD (!) flick One Night in Paris.
