Kelly Clarkson rose to fame singing on national television, so it's no surprise that the original "American Idol" champ soared high with her rendition of the [article id="1677148"]national anthem at Super Bowl XLVI[/article] on Sunday night (February 5).

Wearing a sleek black dress, Miss Independent stood confidently on a small blue-and-white stage at the showdown between the New England Patriots and New York Giants at the Lucas Oil Stadium in Indianapolis. As Clarkson belted out "The Star Spangled Banner" alongside a full marching band and a crowd of children, cameras panned to several members of the teams as they looked toward the sky. Proving herself as a true big-voiced diva, the singer hit all the right notes, adding in some signature riffing at the end of the song.

Even though her performance went smooth, KC admitted having some early jitters about singing the patriotic tune. On Friday, she took to her Who Say account to share her two cents about rehearsal time: "Just finished rehearsing the anthem in Indy ... wow, I'm actually really nervous about singing at the Super Bowl ha!" she wrote. "Here's hoping I nail it and don't screw it up!"

Clarkson's performance was preceded by country music couple Miranda Lambert and Blake Shelton, who delivered a duet of "America the Beautiful" during pre-game festivities.
