Mariah Carey and Nicki Minaj appear to have called a truce.
The American Idol judges, who have been making catty digs at each other on the panel since the series began, were spotted having a civil conversation with each other backstage, reported E! News.
Contestant Angie Miller said: "Nicki completely complimented Mariah! They have a secret friendship, I'm telling you! It's cool that they actually got along tonight."
Fellow singer Kree Harrison added: "Something was in the air. But I'm happy. Maybe they felt some of our girl power."
The episode began with the pair disagreeing over Kree's performance of The Black Crowes' song She Talks To Angels.
While Mariah liked her rendition but thought she may have been trying too hard, Nicki disagreed, saying: "That was the best performance of the night."
When Mariah tried to explain herself, the Starships singer told her to "simmer down, sir".
The episode will be shown on 5* on April 18.
