Demi Lovato

when he sang the national anthem at the start of the Super Bowl.

When I should have sung the verse''O'er the ramparts we watched, Were so gallantly streaming''(''We watched from the trenches who was flying so gracefully''), repeated the previous line but with a slight variation.

She sang''What so proudly we watched at the twilight's last gleaming''(''what so proudly watched the last gleam of twilight''), which is the same as above but included sang the word''watched ''(''watched'') instead of the word''hail''(''elogiábamos'').

The error, in a Super Bowl has had its flaws like the 850 fans who had to be relocated and another 400 who missed the game to their seats will not be ready in time, generated a great gantidad messages and comments in the network Internet social.

Aguilera's representative did not immediately return calls or emails you asking for a comment.
