Yes. Yes they are. At least according to the new NBC promo for "The Voice." Both Cee Lo and Blake mention in this promo that they are working on a song together, or will be fairly soon. I guess that would be the most unexpected collaboration out of that group. I'm down, I dig them both.

The Voice, also starring Christina Aguilera and Adam Levine, will premiere season 2 after the Super Bowl February 5th on NBC.
