Posh joins Pussycat Dolls for Vegas show

Victoria Beckham will perform live with the Pussycat Dolls, Heat reports.

The Spice Girl will join the group for a one-off performance at Caesar's Palace in Las Vegas.

Alisa Boushey, a spokesperson for the band, explained: "Victoria's been in talks with the Dolls for some time and will be joining them onstage. She would have done it sooner but it's been a question of her busy schedule. But it will be happening very soon."

Beckham will follow in the footsteps of Paris Hilton, Eva Longoria and Scarlett Johansson, who have all taken to the stage with the burlesque troupe turned girl band.

The 34-year-old popstar will also design her own outfit for the show.
