Turn Keri Off! Keri Forgets Lyrics to National Anthem

Here is a video of Keri Hilson forgetting the lyrics to the National Anthem at a Atlanta Hawks vs. LA Lakers game.

I have 2 questions for Keri:

1.)How are you a "singer" and forget the lyrics?
2.)How are you a "sports fan" and for sports fan?

Unfortunately, Keri Hilson will be singing the National Anthem again at the Yankees vs. Red Sox games. No Good.
