The Super Bowl is the pinnacle of perfection for the entire NFL. Apparently that's not the case for the entertainment that performs at the biggest event in America.

That's not how it's done... Here's what it's supposed to be:

What so proudly we hailed at the twilight's last gleaming?
Whose broad stripes and bright stars, through the perilous fight,
O'er the ramparts we watched, were so gallantly streaming

Here's what Christina did (See the flub at about the 55 second mark):

What so proudly we hailed at the twilight's last gleaming?
Whose broad stripes and bright stars, through the perilous fight,
What so proudly we watched, were so gallantly streaming

Nice work Christina. Better luck next year.
