Mariah Carey's husband Nick Cannon stopped by The View Wednesday to clear up rumors that a feud is brewing between his wife and rapper Nicki Minaj on the set of American Idol, where Mariah and Nicki are new judges this season.  Not only did the America's Got Talent host refute claims that his wife is dueling with the "Starships" singer, he also insinuated that American Idol producers leaked the fight footage to gossip site TMZ.com, which he said "saddened" him.
