"I had been singing that song my entire life. I was the youngest anthem singer in my hometown of Pittsburgh. I sang for the Steelers... I think (I was) seven or eight. I would sing for them. I think (I) had a moment where I was at the Super Bowl at 30 years old. I took in the moment a little bit too much. Shoot me for appreciating the moment but here I am at the Super Bowl... and then that night I knew, I just made myself a Trivial Pursuit question." Christina Aguilera still can't believe she messed up the lyrics to the National Anthem at the Super Bowl in February (11).
