A person familiar with the plans for the Super Bowl halftime show tells The Associated Press that R&B star Usher and former Guns 'N Roses guitarist Slash are slated to make surprise appearances Sunday.
The person spoke to the AP on condition of anonymity Wednesday, because the musicians' performances were not going to be announced before the game.
The NFL said in November that the Black Eyed Peas would be the featured Super Bowl halftime performer. Past halftime acts have included U2, the Rolling Stones, Bruce Springsteen & The E Street Band, Paul McCartney and Prince.
