Britney Spears Joins The Pussycat Dolls

Not content with her cameo appearances in How I Met Your Mother, Britney Spears has now decided to grace a Pussycat Dolls video with her presence.

The troubled star joined the girl group for the shoot in Burbank, California yesterday, according to Access Hollywood.

The promo is for the band's latest single When I Grow Up, from their forthcoming second album.

It is the second time Spears has performed with the Don't Cha hitmakers. She previously joined them on stage during a private gig at her older brother Bryan's birthday party in 2004.
