NEW ORLEANS (February 1, 2013)--Beyonce admits she did sing the national anthem to a recorded track at the inauguration, but says she won’t lip-sync Sunday at the Super Bowl.

She said says she didn't have time to rehearse with the orchestra before the inauguration and she wanted to make President Barack Obama and the country proud of her.

She promised she would sing live at the halftime show on Sunday and poked fun at reporters by opening her news conference by singing the anthem a cappella, then saying, "Any questions?"

And when asked if she'll have any collaborators on Sunday, Beyonce' coyly said she couldn’t give any details.
