"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," Fox said in a media statement obtained by Reuters.
"Nicki Minaj is a superstar who brought a level of honesty and passion to American Idol and who had a tremendous positive impact on so many contestants this season. Given her extremely busy career, we understand and respect her decision and wish her the best," the network reportedly added.
Fox made its statement after Carey and Minaj both announced their Idol departures via Twitter.
"Thank you American Idol for a life changing experience! Wouldn't trade it for the world! Time to focus on the Music!!! Mmmuuuaahhh!!!" Minaj tweeted Wednesday.
"W/ global success of '#Beautiful' (#1 in 30+ countries so far) @MariahCarey confirms world tour & says goodbye 2 Idol," Carey's public relations firm PMK BNC tweeted yesterday.
Earlier this month, Fox had confirmed prior reports that the network was considering a drastic shakeup that could replace American Idol's entire judging panel for the show's upcoming thirteenth season in an attempt to boost its steady-declining ratings.
