ARLINGTON, Texas: Christina Aguilera says she flubbed a line as she belted out the US national anthem at the start of the Super Bowl Sunday night after getting lost in the moment and losing her place. “I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through,” she said in a statement after the performance. When she was supposed to sing the line “O'er the ramparts we watched, were so gallantly streaming,” she instead repeated an earlier line, with a slight variation. She sang, “What so proudly we watched at the twilight's last reaming,” repeating and mangling an earlier lyric, with the word ‘watched' instead of ‘hailed' and ‘reaming' instead of `gleaming.' The mistake immediately set social networks abuzz with people commenting on the error. Aguilera, who took the stage in a black dress, was returning to the Super Bowl after being one of the performers during the halftime show in Atlanta in 2000. Black Eyed Peas also gave a performance at the Super Bowl halftime show. Absurd, gauche and oddly appropriate. Those were some of the begrudgingly positive reviews of their brief set at the Super Bowl halftime show Sunday. The chart-topping foursome, famed for frustratingly catchy dance tunes such as “Let's Get It Started” and “I Gotta Feeling,” took to the stage at Cowboys Stadium accompanied by hundreds of dancers wearing LED-covered suits. Following in the footsteps of such venerable rock acts as The Who, Bruce Springsteen and the Rolling Stones, the Black Eyed Peas were the first hip-hop act to take center stage at America's biggest sporting event. The football field wasn't the only place fans could get a glimpse of stars at the Super Bowl — there were plenty of famous faces watching the game as well. Celebrities streamed into Cowboys Stadium Sunday afternoon to watch the matchup between the Pittsburgh Steelers and the Green Bay Packers. Hugh Jackman, John Travolta, Adam Sandler, Jennifer Aniston, Catherine Zeta-Jones and Micheal Douglas were among the attendees. Owen Wilson and Jamie Foxx — who both grew up in North Texas — were also there. As Lea Michele of “Glee” sang “America the Beautiful,” the gigantic screen in the middle of the stadium flashed to former president George W. Bush and former first lady Laura Bush.
