The Voice coaches call out the biggest divas! It seems all the coaches want to point fingers at each other when it comes to who’s the most demanding behind the scenes. Adam Levine jokingly tells Extra that Blake Shelton is the one who is screaming, “Where in the hell is my leather cowboy hat?” While, Blake tells People magazine that Christina Aguilera is the diva on set. Diva or not, all four coaches, including Cee Lo Green get along with each other well. Adam and Blake recently appeared on the cover of People together.
