Beyonce has reportedly been taking pole dancing classes to get into shape for the Super Bowl.
The 31-year-old beauty has been preparing for her Super Bowl XLVII halftime show appearance in New Orleans tomorrow (03.02.13), and sources claim her rehearsals suggest a raunchy performance.
A source told the Daily Star newspaper: ''Beyonce and her dancers were rehearsing sexy stretches with some stripper poles this week.
''Who knows if they'll use them in the actual performance, but she was grinding away on one like a professional.''
The 'Love On Top' hitmaker admitted she is ''nervous'' about the halftime show, but she's set to ''surprise everybody'' with her performance.
She said: ''I am ready to surprise everybody and show you what I've got.
''I'm very nervous but very excited. I have trained hard and I'm feeling absolutely fantastic.''
Meanwhile, the US national anthem will be performed by Alicia Keys, and intrigue is already high for Kate Upton's new Mercedes advert.
The 20-year-old model will appear in a slinky white ballgown for the £10 million campaign to be aired during the Super Bowl.
A teaser clip - which has since amassed 5.8 million hits online - hinted she will be seen stripping off for a saucy car wash scene.
