Either Nick Cannon knows his wife Mariah Carey is super talented... or he just thinks she's a total diva!

The America's Got Talent host revealed that he thinks American Idol is going to have to pay a pretty hefty fee if they want his lady love as a judge next season. "I don't know if they can afford Mariah Carey," he told TMZ. "That's a lot of money. If they gave Jennifer Lopez $20 million, they might have to double that!"

Obviously, there is a bit of cynicism to Nick's comment, but, he's sort of right -- chances are Idol isn't going to be facing any discounts if they want to replace J.Lo with a name as big as Mariah! On the other hand, Mariah is only one of the rumored ladies to be in talks to step in for the show's 12th season. Other superstars like Miley Cyrus and Fergie are also names that have been tossed around.
