beyonce lip synced inauguration. beyonce super bowl.Beyonce answered critics of her Inauguration Day performance the best way she could -- with another sterling performance of the national anthem.

The difference?

On Thursday, it was live: She admitted during her Super Bowl news conference that when she performed for President Barack Obama and the nation, she decided to sing to a prerecorded track because she didn't have time to practice. Calling herself a self-proclaimed 'perfectionist,' she said wanted the day to go off without a hitch.

'I practice until my feet bleed and I did not have time to rehearse with the orchestra,' she said, adding that she was also emotional that day. 'Due to no proper sound check, I did not feel comfortable taking a risk. It was about the president and the inauguration, and I wanted to make him and my country proud, 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.'

It was the superstar's first public comments on what has become known as 'Beyonce-gate.' Her rendition of the anthem at the inauguration was critically praised, but it came under scrutiny less than a day later when a representative from the U.S. Marine Band said Beyonce wasn't singing live and the band's accompanying performance was taped. Shortly after, the group backed off it.
