Jennifer Lopez and Steven Tyler may be fleeing, but American Idol will still have star power if it succeeds in snagging Mariah Carey as a host. The singer is reportedly in the final stages of signing on to be the newest judge of the long-running talent show. Her proposed salary is rumored to be more than $17 million for one season. When the whispers started, her famous husband wasn't so sure. "I don't know if they can afford Mariah Carey," Nick Cannon told TMZ. "That's a lot of money."
