Tensions are reportedly running his behind the scenes at "The Voice," no matter how chipper the chair-spinners look on the air. In particular, Adam Levine is apparently feuding with fellow judge Pharrell Williams, as Levine is "feeling shafted by Pharrell behind-the-scenes," a source tells Radar Online. "Not only is Pharrell taking the contestants that Adam would have generally locked in with ease, but he is also a favorite among the production staff."

Ouch. Nobody wants to feel like the production staff's passing them over for the newer, more be-hatted model. Although, according to the source, that staff may have perfectly good grounds for not favoring Levine: "Adam is just jaded after doing it for so many seasons," the source adds. "Production staff are saying that not only does Adam act like an a--hole, but he is totally jealous of Pharrell, and this season has brought out his true colors."
