MUMBAI: American Idol judge Mariah Carey plans to quit the musical reality show due to the growing difference between her and co-judge Nicki Minaj, according to various reports.

According to agencies, a source told Fox News, ''Mariah doesn't want to come back. Nicki is really disrespecting her, and she's tired of trying to bite her tongue all the time.”

Meanwhile, agencies have reported that singer Nick Cannon has blasted the channel and American Idol producers for perpetuating a feud between his wife Carey and another judge Minaj.

"When you see someone like my wife, who tries to remain classy and tries to take the high road, it feels like everybody else around it - including the network and the producers - feed into this whole sound bite drama. It feels like it lacks substance," he said on a TV show.

Rock legend Steven Tyler who was a judge on 'American Idol' for two seasons had advised Carey and Minaj to be professional and focus on the contestants.
