God bless America, the girl can sing.
Kris Allen and Jordin Sparks did the National Anthem honors at the NFC and AFC conference championships, respectively, making it an American Idol year for the end season. Make that two years of football + American Idol since, Jennifer Hudson sang at the Super Bowl last year. Clearly, if you want someone who you know can belt it out get an Idol.
And if you want a blonde country singer who can sing in tune, call Carrie Underwood. Watch the video of her performance after the jump.
