*Nick Cannon is speaking out about the feud going on between his wife Mariah Carey and her “American Idol” nemesis Nicki Minaj, claiming the network and show producers have been trying to milk it for all it’s worth.

“She didn’t sign up for that,” he said to LA’s KTLA-TV morning show host Sam Rubin (video below). On air, Cannon accused “someone behind the scenes perpetuating” the conflict. Once the camera was off, Cannon blamed Fox Alternative Entertainment chief Mike Darnell for bringing Minaj onto the show. “No one thought it was a good idea then and no one thinks it is a good idea now,” Cannon said.

Meanwhile Deadline.com has learned new details about “Idol” and former judge Jennifer Lopez. The singer will use Season 12’s May 16th finale to debut her new single “Live It Up” from her 8th album. It is being released through producer RedOne’s 2101 label that is distributed by Capitol Music which signed her to a big new record deal.

Also Fox is still desperate to bring Lopez back to the show next year after its feeble attempt to replace Mariah with J-Lo this season didn’t go anywhere. An insider tells Deadline’s Nikki Finke about Lopez: ”Fox is chasing her. They want her back. She has not made her mind up about it. She is on the fence. They wanted her to replace Mariah. There was no way she was going to do that. They started talking to her hard about next year. She really liked doing it but big question if she should do it again.”

Cannon was doing publicity for his own show, “America’s Got Talent,” which he hosts again starting June 4th. This morning, he also raised doubts that Carey would be coming back to the once-dominant show next year if asked.

“If they get it stable she might relook at it, but she doesn’t want to be a part of anything unstable,” he told KTLA’s Sam Rubin.

This season has set record lows.
