There hasn't been a diva-off at the American Idol judges table this season... yet.

At the Season 9 finale of So You Think You Can Dance on Tuesday night, judge Nigel Lythgoe denied rumors of a feud between newly announced Idol judges Mariah Carey and Nicki Minaj. "Why would there be?" the Idol producer told TVGuide.com. "It's not about them. They know that. It's about the kids that come out there. It really has already become very constructive to the point of we'll say, 'Oh for Christ's sake, shut up. Let's move on.' If they're saying 'no,' they've got to tell them for half an hour why they're saying 'no' and how they can improve and come back."
