Although the platform was small, Christina was on one of the biggest stages in the world when she mixed up the words to the National Anthem during the most watched Super Bowl ever. During Super Bowl XLV, the Grammy winner sang "What so proudly we watched at the twilight's last gleaming," instead of "O'er the ramparts we watched, were so gallantly streaming." "I took in the moment a little bit too much," the singer told Ellen DeGeneres, suggesting that she was overwhelmed by the honor of performing at such a huge event. "Shoot me for appreciating the moment."
