Another war has begun on “American Idol” – and this time it’s not Mariah Carey vs. Nicki Minaj.

It's Mariah Carey vs. JLO. 

The Hollywood Reporter is reporting that “American Idol” producers wanted to have “Jenny From the Block” back as a judge in the singing competition mid-season and wanted to drop Carey.

But the part-Venezuelan diva wasn’t having it, and her team threatened to sue the show’s producers if they went through with it.

The entertainment magazine said "Idol" producers were so concerned with the show’s plunging ratings that they devised a plot to get JLO back in the judging panel.The Hollywood Reporter said the show’s producers are still in negotiations with Lopez to make a comeback, since she was such a popular judge during seasons 10 and 11.  

The publication said the effort to replace Carey already started. Minaj, too, is reportedly being replaced along with the entire judging panel, which includes country music star Keith Urban and veteran  music producer and “Idol” judge Randy Jackson.

"This is just another ridiculous Idol judge rumor, likely started by talks of Jennifer performing on the finale," a Fox spokeswoman told The Hollywood Reporter in a statement.

THR reached out to Carey’s camp for comment, but her reps denied the allegations. “Idol” executive producer Nigel Lythgoe also said he had “not been included in any conversation regarding replacing Mariah with Jen this season."

“American Idol” has been struggling with their ratings for the past few seasons, but last week’s ratings showed that “Idol” is slipping fast as rival singing competition show “The Voice” gains momentum.
