"I think Nigel [Lythgoe - the show's producer] really admired her talent and always treated her like the queen and the legend that she is."
He added that he thought Carey was more likely to be referring to her well-publicised feud with rapper and fellow Idol judge Nicki Minaj, in which the pair had a spat during auditions and continued to pick at each other throughout the rest of the 2011 season.
"But honestly there was no need for all that...I don't get why she felt that way because as far as I'm concerned she never really had to deal with Miss Minaj. She wasn't even required to talk to her at all, whatsoever.
"Her only job was to come in, sit down in a panel and give her comments to the singers and go home and get paid $18 million.
"If that's abusive, then I really want to be abused by Idol."
