Recently there were rumors that Madonna's Super Bowl halftime show would include LMFAO, Nicki Minaj and M.I.A. Now Cee-Lo Green is another artist whose name is in the mix.

Word is that Madge somehow managed to squeeze Cee-Lo into her 12-minute set. (Think this might have something to do with the fact that Green is a judge on "The Voice", which just so happens to make its season premiere after the Super Bowl?)

No official word from Madonna herself, but TheInsider.com reports, "We're told for the past two weeks Cee Lo has been traveling to New York to practice with Madonna."
