Every year, celebrities flock to the Super Bowl to promote their latest projects, have a good time, or both. This year was no exception. Many stars descended upon Indianapolis in the week leading up to the game.

Former "American Idol" winner Jordin Sparks was there. She's knows a thing or two about football and the Super Bowl - her father, Phillippi Sparks, once played for the New York Giants, and she sang the national anthem at the 2008 Super Bowl, won by the G-Men over the New England Patriots.

Sparks said over the weekend she wished it was her singing the national anthem at Sunday's game and not fellow "Idol" winner Kelly Clarkson. But Sparks was confident that Clarkson would deliver a solid rendition of "The Star-Spangled Banner" at this year's game, despite Clarkson stating on Twitter that she was feeling nervous. Sparks said, "I'm excited for her, she's going to be absolutely fine but I had butterflies too. I was so nervous, sick to my stomach, I thought I was going to fall on my everything, I thought everything was going to go wrong."

Clarkson did not have a Christina Aguilera moment Sunday while performing the national anthem at the Super Bowl at Lucas Oil Stadium in Indianapolis. Unlike Aguilera, who muffed the lyrics to "The Star-Spangled Banner" at last year's Big Game, Clarkson delivered a clean rendition of the song.

Clarkson wore a simple black dress, with Zooey Deschanel-esque bangs, for the occasion. She was backed by the Indianapolis Children's Choir.

While in Indy, ABC News Radio caught up with David Arquette, who recently struggled with alcoholism. He said he was feeling "really good," adding, "I eat a little food, have a cup of coffee…and I'm ready to go."

Snoop Dogg was in Indy, too. When asked why he never performs the national anthem at a football game, he jokingly sang, "Oh say can you see the bud I just smoked."
