The '4 Minutes' singer reportedly has been rehearsing with the former Goodie Mob star for the upcoming event.
Rumor has it, there's a secret guest Madonna is preparing for her much-awaited performance at the upcoming Super Bowl XLVI. According to The Insider, the Material Girl will welcome "The Voice" judge and vocal coach Cee-Lo Green during her headlining bill.
The Gnarls Barkley member reportedly has been traveling to New York to do rehearsals with Madge for the upcoming event. The "F**k You" hitmaker is expected to bring a new sound to some of her classic hits when they join forces during the halftime show.
The 2012 Super Bowl itself is going to take place at Lucas Oil Stadium in Indianapolis on February 5. Madge is expected to showcase the first single from her new album "M.D.N.A." along with M.I.A. and Nicki Minaj.
Madge herself refused to reveal much when being asked about her Super Bowl performance recently. "Pom poms. That's all I can tell you," she told MTV News. To ABC News, she said, "I have eight minutes to set up my stage, 12 minutes to put on the greatest show on earth, and I have seven minutes to take it down so that football field is clean for the second half of the game."
"That's the challenge. How do you do that? I actually wanted to have 100 drummers come from the ceiling, a drumline from the ceiling," she teased.
