Kanye is not sure if Idol is in his wheelhouse but looks like A.I. would match Mariah's salary by paying them both $18 million a year! 

It looks like Nicki Minaj is either close to signing a deal or has signed one to become a judge, but we're told producers may well add a 4th judge. The frontrunners are Keith Urban, Brad Paisley and Enrique Iglesias, but Kanye would clearly trump them all.
