( CNN ) -- There wo n't just be a new winner next season on `` American Idol . '' Most everything about the show may be new . Weeks after Randy Jackson announced his departure from Fox 's long-running music talent show , two of his fellow judges -- Mariah Carey and Nicki Minaj -- followed him out the door Thursday . That leaves only one `` Idol '' judge left in crooner Keith Urban -- for now . News of Carey 's departure came out first Thursday , in the form of a tweet posted on her official account that stated she was saying `` goodbye 2 idol '' ( and , simultaneously , announced a new world tour ) . Players behind `` American Idol '' -- namely Fox , FremantleMedia and 19 Entertainment -- confirmed her departure 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 , '' they said . `` We know she will remain an inspiration to 'Idol ' hopefuls for many seasons to come . '' Minaj followed up a short time later with a tweet of her own , making her exit official , also after a lone season . `` Thank you American Idol for a life changing experience ! Would n't trade it for the world ! '' the rapper wrote . `` Time to focus on the Music ! ! ! Mmmuuuaahhh ! ! ! '' After this tweet , Fox , FreemantleMedia and 19 Entertainment issued another statement saying they `` understand and respect her decision '' in light of `` her extremely busy career . '' `` 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 , '' they said . The two performers had been brought on following the exits of judges Jennifer Lopez and Steven Tyler , hoping to bolster the show 's ratings . `` Idol '' had topped the Nielsen charts as America 's most watched program for eight years running . But that streak ended in 2012 , and since then the show 's producers have made several changes . This season 's finale was earlier this month . Carey and Minaj , though , ended up generating headlines more for their reported tiff than they did for bringing in more viewers . Both of them join Jackson , who had been the only judge remaining from the program 's 2002 debut . Earlier this month , he announced he had voted himself off the show . `` It 's been a life-changing opportunity , but I am looking forward to focusing on my company , Dream Merchant 21 , and other business ventures , '' the musician and producer said .
NEW : Minaj `` is a superstar who brought ... honesty and passion , '' show 's producers say . Minaj and Mariah Carey both announce their exits from `` American Idol '' after 1 season . The two performers had clashed and were n't able to bolster the program 's ratings . Randy Jackson announced he was leaving `` American Idol '' earlier this month .
