Before the New Orleans Saints and the Indianapolis Colts hit the field at this Sunday’s Super Bowl game, Carrie Underwood takes the stage to sing the National Anthem. How does the country star feel about kicking off the biggest football game of the year? “I am going to be extremely nervous,” Underwood told CMT Insider (via People.com). “If I look like I am about to get sick on the field, I may at any moment during that song.” Queen Latifah also performs in the pre-game festivities while The Who’s Pete Townsend and Roger Daltrey will entertain fans during the halftime show.
