Nicki Minaj will be joining Mariah Carey as a judge on the Fox singing competition, Us Weekly reports. Although the news has yet to be officially confirmed, sources tell the mag the rapper is definitely on board.

"I'm not sure the deal is completely done yet, but yes, she is definitely doing it. A few more slight things to sign off on but it is happening," a source divulged. Reps for Fox and Minaj had no comment.

Miss Minaj has been one busy bee lately. After touring with X-Factor judge Britney Spears throughout 2011, the "Starships" singer will embark on her own world tour beginning October 21 in England. No word yet on how the chart topper will juggle her performing schedule with A.I tapings.

Also being considered for a judging spot? Nick Jonas and N.E.R.D rapper Pharrell Williams. Longtime judge Randy Jackson is said to be moving into a "mentoring" role on the show, necessitating a male star to fill his vacant judging seat.

Mimi and Nicki on the same show?! That's a whole lot of ego on one stage!
