At a press conference in New Orleans, Beyonce has admitted to lip-syncing the national anthem at President Obama's Inauguration, but for the Super Bowl, she said she will "absolutely be singing live."

Beyonce said for the Inauguration, she did not have time to rehearse with the orchestra.

"It was a live television show. Due to the weather, due to the delay, due to no proper sound check, I did not feel comfortable singing live."

Beyonce said she sang along to her own voice on a prerecorded track.

The superstar addressed the issue moments after she walked into the room on Thursday, asked members of the media to stand, and then launched into an a cappella presentation of the anthem.

"Any questions," she asked? 

The entertainment leading up to the Super Bowl is so A-list, Beyonce may not have the most anticipated performance surrounding Sunday's big game in New Orleans.

Justin Timberlake is scheduled to give his first major musical performance in four years.

Stevie Wonder will perform at an outdoor concert. CeeLo is reuniting with his old hip-hop clique, Goodie Mob, and Rascal Flatts will team up with Journey for a concert. And that's only a fraction of the all-star events.

Indeed, much of the emphasis in the days leading up to the big event has very little to do with the game.

Lil Wayne is throwing a major bash in his hometown, Jay-Z will hold court at another event the evening before his wife, Beyonce, performs at halftime, and Jamie Foxx is due to give a private concert - and that's just the lineup for Saturday.
