Mariah Carey will not return to “American Idol” next season.

The pop star’s publicity firm, PMK BNC, tweeted Thursday that Carey is departing the Fox series and planning a world tour in support of her new single “Beautiful.”

Carey became a new judge on “Idol” last year along with Keith Urban and Nicki Minaj. She and Minaj made headlines when they bickered on and off the airwaves.

Fox and FremantleMedia said in a statement:

Mariah Carey is a true global icon – one of the most accomplished artists on the planet – and we feel  extremely fortunate  that she was able to bring her  wisdom  and experience to the “American Idol” contestants this season.  We know she will remain an inspiration to “Idol” hopefuls for many seasons to come.”

Randy Jackson recently announced that he was also leaving the show.
