The 'Starships' singer looks to be joining Mariah Carey as a new judge on the Fox competition, Us Weekly claims.
While one source stated that Minaj is "100% confirmed" to join the show, another insider was more cautious.
"I'm not sure the deal is completely done yet, but yes, she is definitely doing it," the source said. "A few more slight things to sign off on but it is happening."
A number of stars have been linked to the American Idol spots vacated by Jennifer Lopez and Steven Tyler earlier this year.
Nick Jonas recently confirmed on Twitter that he is being considered for the job, while P Diddy and Adam Lambert are among the other names who have been rumoured for the position.
Minaj was recently forced to pull out of a string of concerts because of "vocal cord issues", but responded angrily to fans who complained on her Twitter page.
