The singer was given the chance to sing the national anthem at the opening ceremony of the Super Bowl, the championship game of the National Football League. However, she socked many by repeating a line of the anthem. She repeated the line “What so proudly we watched at the twilight's last gleaming" instead of the line “O'er the ramparts we watched, were so gallantly streaming?"
Now, Christina has offered her apology for the mistake. “I got so caught up in the moment of the song that I lost my place. I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through," Contactmusic quoted the singer as saying.
