Mariah was the first the sign her deal, with Minaj and Urban signing on the dotted line just in the last few days.
"Idol" host Ryan Seacrest tweeted a photo of himself with the judges (see above), writing, "It's official, your new #IdolJudges are @MariahCarey, @NickiMinaj, @KeithUrban & @Yo_RandyJackson!"
It should be known that Mariah Carey and Nicki Minaj have been at Peace at all. So, you should expect a War at JUDGE DESK.
