R & B singer Beyonce has finally "faced the music" and spoken out about her controversial performance nearly two weeks after the grand celebration of the second inauguration of President Barack Obama on January 21.

At the pre-Superbowl press conference held at New Orleans Convention Center Thursday, January 31, the 32-year-old singer admitted using pre-recorded track at the highly celebrated presidential inauguration and attributed her much-criticised move to "being perfectionist" and the day's weather.

"I am a perfectionist ... I did not have time to rehearse with the orchestra [at the Inauguration]. It was a live television show and a very important moment for me," Beyonce said, according to USA Today.

"Due to the weather, due to the delay, due to no proper sound check, I did not feel comfortable taking the risk ... so I decided to sing along with my pre-recorded track, which is very common in the music industry. And I'm very proud of my performance," the 'Crazy in Love' hitmaker was quoted as saying before members of media.

As if still in doubts of whether Blue Ivy's mom can actually sing live in the highly anticipated sports event, a reporter grilled Beyonce if she would perform live this weekend, Sunday.

"I will absolutely be singing live," Beyonce quipped, adding "This is what I was born to do."

To prove that she could perform "The Star-Spangled Banner" at the Super Bowl XLVII, Jay-Z's wife gave the press a taste of what to expect on February 3.

Standing before her dubious and calculating audience, Beyonce sang the National Anthem without assistance.

Half-way into the song, the audience got carried away as seen in the video, giving her a boost for her own and this time, with quite a different rendition of the national anthem.

Watch the video to see a different performance, albeit a rehearsal, of Beyonce's rendition of the national anthem at the press conference.

Beyonce already performed for the annual sports event in 2004. Check out the video below.

And after belting out the most difficult part of the song, she teased her audience with, "Any questions?"

Now the question running in everyone's mind is not just whether or not Beyonce could prove she could sing live when she goes on stage. Critics and Superbowl afficionados are asking if she could top Madonna's performance at last year's Superbowl.

Enstars reported that "Super Bowl XLV1 was the most watched television show in history and the halftime show is considered the biggest musical event of the year." View Madonna's performance at Super Bowl Half-time in 2012 in the video below.
