The Super Bowl XXXVIII halftime show took place on February 1, 2004 at the Reliant Stadium in Houston, Texas as part of Super Bowl XXXVIII. It featured Janet Jackson, Justin Timberlake, P. Diddy, Nelly, Kid Rock, and Jessica Simpson. The halftime show was produced by MTV, and the show was centered on the network's Choose or Lose campaign (the year 2004 was a presidential election year in the United States). Immense controversy arose from an incident during the show in which one of Janet Jackson's breasts – adorned with a nipple shield – was exposed by Justin Timberlake.
