"I don't think they had any intention for us to have a good experience doing that show," said Mariah. "Pitting two females against each other wasn't cool. It should have been about the contestants instead of about some non-existant feud that turned into even more ridiculousness."
"I would never want to be involved with it again," she continued.
Mariah did not stop there, going on to call the long-running show "so boring and fake, I'm sorry."
When speaking to ET about her rumored feud with Nicki Minaj back in 2013 -- while still an Idol judge -- Mariah took a much softer tone.
"This is a very passionate panel," she said. "I think there are a lot of strong personalities and, starting this process, I thought it was a possibility there could be differences of opinions. The fighting is what it is. This is American Idol, it's bigger than all that. It's bigger than some stupid, trumped-up thing. It's about the next superstar."
