The Mariah Carey-Nicki Minaj American Idol rivalry carried over to the divas’ departure from the show, with Minaj stepping on Carey’s toes and announcing her own departure on Twitter shortly after Carey had done the same, also on Twitter. “Thank you American Idol for a life changing experience!,” Minaj wrote. “Wouldn’t trade it for the world! Time to focus on the Music!!! Mmmuuuaahhh!!!”

Minaj joins fellow judges Carey and Randy Jackson on the list of Idol departures as the veteran series wrapped its lowest-rated season. We’ve yet to hear from judge Keith Urban and executive producer Nigel Lythgoe, both of whom are rumored to also depart. Fox and Idol producers seem to have already moved on, with Jennifer Hudson in talks for a spot on the judging panel next season, possibly alongside other well-known Idol alums.

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,” Fox and Idol producers FremantleMedia and 19 Entertainment said in a joint statement. “Given her extremely busy career, we understand and respect her decision and wish her the best.”
