Watch the Super Bowl National Anthem Mashup
Some of the favorite pop stars have delivered the national anthem at the Super Bowl. Alicia Keys is set to do the deed today (Feb. 3), following up last year's belter Kelly Clarkson. We hope Miss Keys delivers it flawlessly, which isn't always easy. Just ask Christina Aguilera, who effed it up royally in 2011.
Yeah, she's featured here.
