Alicia Keys will perform the National Anthem at Super Bowl XLVIII.  

The Super Bowl teams will be determined this Sunday, when the San Francisco 49ers play the Atlanta Falcons in the NFC championship game, and the Baltimore Ravens face the New England Patriots in the AFC championship game.

Beyonce will be the star of the halftime show. She sang the national anthem at the 2004 NFL title game in her hometown of Houston.

Past national anthem performers include Kelly Clarkson last year, as well as Whitney Houston, Billy Joel and Mariah Carey.

Alicia is no stranger to the Super Bowl.  She performed at the Super Bowl in 2008.
