Aguilera managed to sing the wrong words during her performance of the iconic song – she sang "What so proudly we watched at the twilight's last reaming" instead of the real lyrics ""O'er the ramparts we watched were so gallantly streaming."
We have to admit, we feel really bad for Aguilera – after all, we'd be nervous too if millions of eyes were watching us sing.
The web isn't so forgiving. Almost immediately, Twitter and the web were buzzing with talk of Christina Aguilera's National Anthem mishap.
I wonder if Christina Aguilera would get the lyrics right to happy birthday....?" one tweeter wrote.
Christina Aguilera: Worst. National Anthem. Ever," wrote another Twitter user.
"Christina Aguilera, FTW. Maybe a teleprompter next time when she needs to say "USA?" yet another mused.
That's one of the best – or worst, if it happens to you – things about the web: your minor screw-ups can now be seen by millions in a matter of seconds.
