Christina Aguilera Super Bowl 2011 National Anthem Mistake Messes Up Err...

  She is an amazing singer, but this is simply unbelievable and unacceptable.
  First, I thought, since I do not remember the lyrics of this song, it could happen to anyone especially if one is nervous. Then I thought again. No, this is not possible.
 I am not an American citizen. but I do remember the lyrics for my country's National Anthem perfectly.
It's not like somebody taught me in school, but by the time I was in second grade, I had them memorized word by word
 Come on, Christina, step up! I know that you just went through divorce, and are probably very frustrated because you can only get not-so-great guys, but singing is what you do for living, and you do that better than most famous singers. And to sing National Anthem at Super Bowl has been your dream since you were little.
 Well, you let us down this time by doing something you are normally great at. Maybe next time, you can impress us by doing something you normally suck at- Bring a good-looking, famous guy to a red carpet event.
