What A Doll!

Is Britney Spears joining the Pussycat Dolls? Nah! But she is making a cameo in their new music video for "When I Grow Up." The weird part is that she never interacted with the group! While she shot on the Warner Bros. lot, the Dolls shot in Hollywood. "It was carefully planned out," a set source tells Us Weekly. But watching the video, you'd never know! In Brit's scene, she and PCD pass each other in traffic and wave. "It is a very short sequence, but she [Britney] had a lot of fun with it," the source says. "Britney really likes the Dolls' music and when she saw them on the MTV [Movie Awards], she was totally down to do the video." So how'd Brit look? "Hot and blonde," the insider says. Can't wait to see it!
