Jordin to perform at Commander-in-Chief's Inaugural Ball

Jordin Sparks has a busy next three days ahead of her. Not only will she be singing "The Star-Spangled Banner" at tomorrow's NFC Championship game between the Arizona Cardinals and the Philadelphia Eagles in Glendale, Ariz., but she will make an appearance at one of President-elect Barack Obama's inaugural balls on Tuesday.

Jordin's mom confirmed that she will in face be performing at the Commander-in-Chief Inaugural Ball, hosted by the president-elect, on Tuesday. The ball, which was conceived by President George W. Bush in 2005, will be broadcast live to American forces around the globe. George Lopez and Miss America Kirsten Haglund will also appear.

Jordin will not be the only Idol alum in attendance at one of the many inaugural bashes. It was announced late last year that Daughtry would be headlining the Congressional Youth Leadership Council's ball.
