The battle for attention between American Idol divas Mariah Carey and Nicki Minaj continued right until the end.

Shortly after Mariah announced her official departure from American Idol on Thursday afternoon, Nicki had to have the last word, and announced her split from the show.

She tweeted, "Thank you American Idol for a life changing experience! Wouldn't trade it for the world! Time to focus on the Music!!! Mmmuuuaahhh!!!"

Keith Urban remains the final question mark as to whether he'll stay or go on the Idol judges' panel. Randy Jackson previously announced his plans to leave Idol during a telecast.
