Did you watch Christina Aguilera sing the Super Bowl XLV 2011 national anthem and totally screw up the lyrics (video)?

To her credit, Christina Aguilera’s “Star Spangled Banner” lyrics mess up wasn’t that epic, but how many times has she sung the National Anthem live?

In case you missed it, watch Christina Aguilera sing the Super Bowl 2011 National Anthem forgetting “O’er the ramparts we watched” and instead singing “What so proudly we watched.”

Should we cut Christina some slack?
