Christina Aguilera Flubs Lyrics To National Anthem

Many people call "The Star Spangled Banner" one of the hardest songs to sing, and Christina Aguilera experienced that first hand. The pop star had no problem hitting all the high notes before Super Bowl 45 in Arlington, Texas, but she did have a problem remembering all the words. Aguilera forgot to sing "O're the ramparts we watched were so gallantly streaming," singing "What so proudly we watched at the twilight's last gleaming." She appeared to have realized her mistake mid-line, and some of the words in that line were hard to understand. But she did regain her footing, finishing with her usual vocal acrobatics just as the fighter jets flew over Cowboys Stadium.
