The singer, who fumbled through the lines of the National Anthem Sunday, is getting some love from fellow Super Bowl performer, Fergie of the Black Eyed Peas.
"I completely understand. She's one of the best singers of our time," the "Fergalicious" songstress told sportscaster Dan Patrick on his Sports Illustrated radio show Monday morning. "Nobody can take that away from [her]. But you get nervous at these things. We're human."
The singer, who took to the stage with her bandmates for a flashy, rousing half-time show, said nerves probably caused Aguilera's blunder.
"It's such a huge venue, your nerves take a hold of you," she said.
Added the singer: "Some of my notes were pitchy to me. [But] it was so exhilarating. The whole thing. It was so big. That's a once-in-a-lifetime thing."
Fellow Anthem singer and "American Idol" vet Jordin Sparks also spoke up in defense of Aguilera: "The test of a true artist is continuing even when things go a little left & not letting people know it did during the performance. I love Xtina."
During the anthem, Aguilera flubbed the fourth line of the song, belting: "What so proudly we watched at the twilight's last reaming," to the bewilderment of somber Super Bowl fans.
The lyrics that should have come at that point in the song: "O'er the ramparts we watch'd, were so gallantly streaming."
Aguilera, who is no stranger to "The Star Spangled Banner" - the "Burlesque" star belted the National Anthem at last year's NBA Game 7 - defended her lyrical slip in a statement to the Wall Street Journal's Speakeasy blog Monday.
"I got so caught up in the moment of the song that I lost my place," she explained.
"I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through."
