NEW YORK (AP) - Mariah Carey says she isn't retuning to "American Idol."

The pop star's publicity firm, PMK BNC, tweeted Thursday that Carey isn't returning to the Fox series and is planning a world tour thanks to the success of her new single, "Beautiful."

Carey became a new judge on "Idol" last year along with Keith Urban and Nicki Minaj. She and Minaj bickered on the show, creating a feud that was uncomfortable for both viewers and contestants.

Randy Jackson announced that he was also leaving the show.

Carey's new single, a Top 20 hit on the Billboard Hot 100 chart, features Miguel.
