Add one Grammy Award winner and one "American Idol" to this year's Super Bowl roster. ALICIA KEYS and JORDIN SPARKS are set to perform before the big game on Sunday in Phoenix, according to the Associated Press, further amping up the musical line-up.

Keys will kick off the pre-game festivities with some of her infectious R&B, while Sparks ("Idol"'s youngest-ever winner) will serenade the Patriots, Giants and viewers everywhere with her rendition of the national anthem, the news agency reports.
