Nicki Minaj is the latest judge to leave American Idol, following Randy Jackson's announcement that he's departing the show after 12 seasons.

A source told US Weekly that the 30-year-old rapper/singer won't be signing on to do another season for the hit-reality singing competition and that Thursday will be her last day.

"It's safe to say she isn't coming back to Idol," the source said. "She's OK with it. She had a great time, but was only going to do one season anyway."

Instead, the Super Bass singer will reportedly use her time to focus on touring, creating a new album, and getting more endorsements.

Fox declined to confirm if the report was true or not. A representative for Minaj did not respond for comment.

Fox sources did confirm that fellow judge Mariah Carey will be getting fired.

"Yes, we want to do a whole new panel-but, just like last time around, it depends on who we get," the source said.

Minaj has been in ongoing feud with co-judge Carey since the season started.

Over the last past week both ladies have encountered intense arguments on the judge's panel, with Minaj even taking to her Twitter account to post that Carey was "bitter" and "insecure."

Although Carey has never defended her behavior off-camera, her husband Nick Cannon recently called the situation between the two women "unfortunate."

Cannon slammed Fox and American Idol for promoting the fights.

"When you see someone like my wife, who tries to remain classy and tries to take the high road, it feels like everybody else around it - including the network and the producers - feed into this whole sound bite drama. It feels like it lacks substance," he said on The Talk.

"I think the producers thought that the feud would bring in ratings at first, but then it got away from them," a source told ABC.com.

In an interview last month with Hollywood Life.com, Minaj said that it was a dream come to true to become apart of the show.

"I think people would rather be surprised. I like to save the mystery and the drama. I never give that away, but you know what? I always say this, and I mean this from the bottom of my heart, that just the people behind the scenes at Idol have been just like a dream to work with and I really, really honestly mean that," she said.
