London - Beyonce has been rehearsing for the Super Bowl for three months.
The 'Diva' singer - who was criticised last week for miming the American national anthem at President Barack Obama's inauguration - has reportedly been preparing to perform live at the high profile sporting event in New Orleans on Sunday (03.02.13) since the end of October.

A source close to the halftime show told EOnline.com: "Rehearsals typically go on for two to three months in advance" and explained that the 31-year-old singer was likely to have signed a deal to perform at the event last summer.
Beyonce is not being paid to perform at the event but her production costs, which are estimated to be in the region of $600,000, will be covered and her show is being sponsored as part of her $50 million deal with her.
The 'Halo' hitmaker - who allegedly mimed 'The Star Spangled Banner' in Washington DC immediately following the president's swearing-in and speech because she only had one night to rehearse with the US Marine Corp Band before the performance - is reportedly feeling the pressure to wow next weekend despite believing she did nothing wrong.
A source close to the 'Diva' singer said she was very disappointed and felt "a technicality which everybody does took away from the beauty of the moment.
"She didn't think there was anything wrong with it. Pavarotti has done it! It was freezing out, and if she messed up just one note, that would have been the story.
"Everybody uses these tracks, and the music director advised it. Any big outdoor live performance is almost always with some kind of track.
