The NFL has been very cautious when it comes to Super Bowl half-time performances ever since Janet Jackson's legendary 'wardrobe malfunction.'  Madonna, who is set to perform at this year's big game, has heard the NFL's plea to keep it clean.  The Material Girl promises all of her material will remain in place.
