Watch Christina Aguilera's National Anthem Rehearsal and Forget the Flub?

Christina Aguilera's National Anthem screw-up was witnessed by an average of 111 million viewers. While singing "The Star-Spangled Banner," instead of "O'er the ramparts we watched, were so gallantly streaming," Aguilera belted out a variation of an earlier line, "What so proudly we watched at the twilight's last gleaming."

"I got so caught up in the moment of the song that I lost my place," said Aguilera, as reported at Us Magazine. "I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through."

Is it hard to believe that the 30-year-old singer, standing in the middle of a packed Super Bowl stadium singing one of the most beloved American songs, could lose her place? For some, it has been, especially when singers are paid hundreds of thousands of dollars to do it.

But perhaps those who can't forgive or forget should watch Christina Aguilera in her National Anthem rehearsal as seen at TMZ. In it, we can see that Aguilera gets it right and does it with the incredible voice that got her famous.

Unfortunately, Christina Aguilera's National Anthem mess is not all as of late. She has had her share of current trouble and the rumors associated with it, as Megan Morris reported in "Is Christina Aguilera Spiraling Out of Control?"

She broke up with her husband Jordan Bratman, but allegedly let new boyfriend Matt Rutler move in even while Bratman was still living at her house, apparently for the sake of Aguilera and Bratman's son Max.

She reportedly shouted and grabbed at "Burlesque" co-star Julianne Hough while the two were at a party in West Hollywood, allegedly threatening to destroy Hough's country music career.

In addition, Aguilera and Rutler allegedly showed up uninvited at Jeremy Renner's 40th birthday party. They apparently got drunk and crashed for a bit in Renner's bed.
