Christina Aguilera committed one of the cardinal sins of live performing , forgetting the lyrics, of one of the most recognized  song in America, The National Anthem.

Christina Aguilera botched the national anthem something fierce before the Super Bowl. Aguilera started out all right, but she had a problem with the ramparts -- specifically, the "O'er the ramparts we watched" line, which she left out altogether.

Aguilera tried to make up for it by combining two lines -- "What so proudly we watched," instead of "What so proudly we hailed", but let's just say that it was too late to reverse the error. Twitter blew up, and all Aguilera could do was to oversing every word from there on out, which she most certainly did.
