In the middle of a heat wave that kept many New Yorkers inside today, fans of Cee Lo Green packed the plaza outside the Today show to see the vivacious singer perform. The Grammy winning performer and judge on NBC’s hit show The Voice, dressed appropriately in white and donning shades, took the stage and wowed fans with a rendition of his hit “Forget You.” With temperatures headed above 100 degrees, many would have preferred to forget the heat, but Green's energy kept the crowd moving.

Green was a sensation this spring during season one of The Voice, the unexpectedly popular singing competition show that drew many fans because of its the positive atmosphere created by the judges and contestants. Green was accompanied as a judge on The Voice by country star Blake Shelton, female pop singer Christina Aguilera and Adam Levine, the front man of rock’s Maroon 5. Auditions are underway for season two.

Speaking with Today host Matt Lauer, Green previewed his upcoming gig in Las Vegas and may have coined a new term by describing the act as “monumentous.” Lauer also teased a confession out of Green about his crush on Pippa Middleton before the singer played a few more numbers for the sweat soaked audience.
