Nick Cannon is apparently serious. The host of the CBS Radio-owned WXRK-FM (92.3) morning show in New York, known for both his acting and the fact that his wife is singer Mariah Carey, has had a simmering feud with Detroit native and rapper Eminem. The artist claims he had a relationship with Carey. What may have pushed their feud to a new level was a track released by Eminem called “The Warning,” and in it he raps, “Mariah, it ever occur to you that I still have pictures,” and also included some details of sex between the two. Cannon said on his radio show he wants to fight Eminem for charity, in a boxing match to put an end to their feud. Cannon said, “We should do it at Joe Louis Arena in Detroit … We’ll do it in the suburbs of Michigan to make him feel more at home. Call Don King; get him on the phone. It’s going down.” – Discuss it.
