LOS ANGELES - Justin Timberlake is the robot in his 'Filthy' video. The 36-year-old singer donned a black turtleneck and glasses to play an inventor unveiling his droid dancer creation to an audience in the promotional film for his comeback single, and in a behind-the-scenes clip, he's now revealed he's also responsible for the automaton's fancy footwork. In the clip, Justin could be seen wearing a unitard and skull cap and was hooked up to motion-capture equipment while the song played in the background.–CM
