It looks like Britney Spears is on a roll when it comes to filming music videos. Fresh off the heels of making a cameo in the newest Pussycat Dolls clip, Brit is now headed to London to shoot the video for her next single, "Radar." Not only will Brit be starring in the video, she'll be co-directing. "She will be behind the camera as much as possible," says her manager Larry Rudolph. "She wants to make sure it's exactly right." As for the video plot? "The theme is her and her girlfriends are going to be looking all around London trying to find a boy who she met in a club," explains Larry. "Every time they think they have him, it's someone else."
