OMG, what do we have here? Looks like we have some surprises in store for the halftime show at Sunday's Super Bowl.

Usher and Slash are heading to the Super Bowl.

A person familiar with the plans for Sunday's halftime show told The Associated Press that R&B star Usher and former Guns 'N Roses guitarist Slash are slated to make surprise appearances.

The person spoke to the AP on condition of anonymity Wednesday, because the musicians' performances were not going to be announced.

Usher and Slash are supposed to join the Black Eyed Peas, who are the main halftime act for Sunday's NFL championship game between the Pittsburgh Steelers and Green Bay Packers at Cowboys Stadium.

Black Eyed Peas member will.i.am is featured on Usher's hit single "O.M.G."
