Carey, 42, might be making her way to the Fox singing competition after Steven Tyler's confirmation that he will not return to the American Idol judges' table and amid buzz that Jennifer Lopez is likely following in his footsteps, reported People Magazine.
"She's in play. They are in serious talks," a source said.
Since the show began switching up the panel when Paula Abdul left in 2009, the only original judge on the panel is Randy Jackson.
Jackson has collaborated with Carey throughout her career and delivered many hits.
