*She took a reported $18 million from “American Idol” in 2012 during her one-season stint as a judge, but that hasn’t stopped her from roasting the struggling singing competition during interviews.

“It’s so boring and so fake,” the 45-year-old star told Australian KIIS FM hosts Kyle and Jackie O on Thursday, according to the Daily Mail.

“I’m sorry, I just think it’s … when I say it’s fake … I mean like you have to make up things to say about people,” she said of the series, which announced its cancellation after a final season next year. “Half the time the performances are good, you just be like ‘it was good’ and you feel like ending it there: ‘You were really good.’”

Carey, who appeared on Season 12 of the show alongside Randy Jackson, Keith Urban and rival Nicki Minaj, said she has no interest in participating in an “Idol” reunion show, either.

“Hell, no! Absolutely not, that was the worst experience of my life,” she said.
