The two divas signed on as rookie judges for the show this past season, but constantly clashed on and off screen.

“W/ global success of #Beautiful (#1 in 30+ countries so far) @MariahCarey confirms world tour & says goodbye 2 Idol,” said a tweet Carey retweeted today from her publicists PMK BNC.

Minaj also confirmed that she’s leaving the Fox singing competition via Twitter on Thursday, sealing the deal with an internet kiss.

“Thank you American Idol for a life changing experience!” Minaj tweeted. “Wouldn’t trade it for the world! Time to focus on the Music!!! Mmmuuuaahhh!!!”

Fox, FremantleMedia and 19 Entertainment called Minaj a “superstar” in a statement regarding her departure, adding, “we wish her the best.”

“Nicki Minaj is a superstar who brought a level of honesty and passion to ‘American Idol and who had a tremendous impact on so many contestants this season,” the statement reads. “Given her extremely busy career, we understand and respect her decision and wish her the best.”

Fox also weighed in on Carey’s decision to move on to greener pastures.

“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,” said Fox and producers FremantleMedia today.
