Christina Aguilera flubbed a line as she belted out the national anthem at the start of the Super Bowl.
When she was supposed to sing the line "O'er the ramparts we watched, were so gallantly streaming?" she instead repeated an earlier line, with a slight variation.
She sang "What so proudly we watched at the twilight's last gleaming," which is the same line from earlier in the song but with the word `watched' instead of the word `hailed.'
The mistake immediately set social networks abuzz with people commenting on the error.
Aguilera's representative did not immediately return a call and e-mail seeking comment.
