Madonna and Justin Timberlake worked together with Timbaland on the song and music video for "4 Minutes." It's a great song. The music video features Madonna and Timberlake dancing in various scenarious including in front of a large digital clock that is counting down from four minutes. They do only have four minutes to save the world after all. They seem to be spending too much time dancing and flirting to save the world but it is a music video. You can watch the video here on Madonna's YouTube channel.
