Christina Aguilera looked and sounded good as she belted out the National Anthem at the beginning of Super Bowl 45. There was just one problem -- Christina apparently forgot to study the lyrics before taking the field.  More after the jump.

She was supposed to sing, "O'er the ramparts we watched, were so gallantly streaming," but instead went with, "What so proudly we watched, at the twilight's last reaming."

In a statement, Christina said, "I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through."
