Cyndi Lauper is now highly criticized on Twitter for changing the lyrics of the US national anthem at the US Open during the remembrance ceremony of the 9/11 10th anniversary.

Cyndi Lauper performed “The Star-Spangled Banner” before the beginning of the women’s final tennis match between Serena Williams and Caroline Wozniacki.

Cyndi Lauper was doing fine until she got to that crucial line regarding ”the ramparts we watched,” the same line that Christina Aguilera famously botched during 2011 Super Bowl.

While Christina Aguilera’s error involved a reference to “the twilight’s last reaming” — a line that surely Francis Scott Key did not have in mind when he wrote the poem that inspired America’s definitive piece of musical patriotism — Cyndi Lauper changed the lyric less significantly.

Cyndi Lauper sang “O’er the ramparts, we watched as our flag was still streaming,” instead of the usual “O’er the ramparts we watch’d were so gallantly streaming.”

After this incident, all tweeters went nuts and, in yet another irony, blasted Cyndi Lauper for making such a terrible mistake while making an error of their own and completely misspelling her name –“Yes, Cindy Lauper has been a trending topic tonight on the social networking site.”
