britney spearsBritney Spears has reportedly filmed a cameo appearance in the Pussycat Dolls’ new music video - but neither sings or dances in the clip.

Britney shot her scenes to accompany the group’s new single ‘When I Grow Up’ in Burbank, California on Wednesday and an on-set source told Us Weekly that the video is centred around singing while driving around in cars: “It was carefully planned out.

“In the scene shot, Britney is driving in a car. They all wave at each other as they are passing in traffic - that is it.

“It is a very short sequence, but [Britney] had a lot of fun with it. Britney really likes the Dolls’ music and when she saw them on the MTV [Movie Awards at the weekend], she was totally down to do the video.

“It is genius and you will love it! [And] of course, Britney looks hot and blonde.”

As well as this cameo and her small role in sitcom How I Met Your Mother, Britney is said to be in the early stages of recording her next album.

A source close to the singer’s family added: “She’s taking baby steps with everything at the moment. Trying to get back on her feet without rushing it. But she’s in no doubt that she wants to get back to the top.”
