X-Tina fluffs National Anthem

Christina Aguilera forgot the lyrics to the National Anthem during her Super Bowl performance on Sunday.

The singer was supposed to sing the line 'O'er the ramparts we watched, were so gallantly streaming' but instead she repeated an earlier line with a slight variation.

She sang:'What so proudly we watched at the twilight's last gleaming' - the same line from earlier in the song but with the line 'watched' instead of 'hailed'.

According to Yahoo, she said she made the mistake after getting lost in the moment. She said: 'I can only hope that everyone could feel my love for this country and that the true spirit of it's anthem still came through.'
