Christina Aguilera of 'The Voice' explained her gaffe at the 2011 Super Bowl where she infamously flubbed the lyrics to the national anthem. Turns out, the singer simply got lost in the moment, she said on 'The Ellen DeGeneres Show' (weekdays, syndicated).

"I've been singing that song my entire life. I was known as the youngest anthem singer in my hometown," said Aguilera. "[But] I had a moment where I was at the Super Bowl at 30 years old and, you know, I took in the moment a little bit too much."

"That night I knew. I was like, 'I just made myself a Trivial Pursuit question,'" she continued. "But, you know, I had a really good laugh about it. And you get over things and you get back up again."
