Everyone knows that forgetting the lyrics to the National Anthem is not a very good thing to do, especially when you’re a well-known singer. Christina Aguilera sang the “Star-Spangled Banner” before the Super Bowl kick-off but it went downhill for her when she forgot one line and replaced it with another one. Instead of singing “'O'er the ramparts we watched were so gallantly streaming”, she replaced it with “what so proudly we watched at the twilight's last [unintelligable lyric]". There were reactions from the crowd despite the anthem was being sung. Sources said that she was devastated because she let everyone down. That’s why we can’t say anything bad against her because we know she meant well. We just hope it doesn’t happen again.
