LOS ANGELES, California (X17online) - Britney Spears will be making a cameo in the Pussycat Dolls' latest video, "When I Grow Up," according to Us Weekly.

Spears shot her scenes for the Pussycat Dolls' new single on the Warner Bros. lot in Burbank, California yesterday afternoon, while the pop group filmed their scenes in Hollywood.

An on set insider told the magazine, "It was carefully planned out. In the scene shot [Wednesday], 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 she had a lot of fun with it. Britney really likes the Dolls' music and when she saw them on the MTV Movie Awards, she was totally down to do the video." The insider added, "Of course, Britney looks hot and blonde."
