Christina Aguilera Flubs National Anthem

Christina Aguilera belted out the National Anthem in typical Christina style, only one hitch...  Christina decided to go ad-lib about half way through the National Anthem.  She has not had a good year so far, and last night's performance at the Super Bowl didn't help the situation.  Click 'READ MORE' to listen to the flubbed line...

WOOPS!  The correct lyrics are, "O'er the ramparts we watched, were so gallantly streaming," but instead Christina sang, "What so proudly we watched, at the twilight's last reaming."

Do you think Christina's career is going downhill?  No recent hit on the billboard charts and the last movie she was in was Burlesque, which lost $20 Million.
