A different competition is going on over at American Idol between judges Mariah Carey and Nicki Minaj. 

The two divas had a falling out on Tuesday during the taping of auditions in Charlotte, N.C.  

In a video obtained by TMZ, Nicki is heard shouting, "I told them I'm not f*ckin' putting up with her f**kin' highness over there."

Fellow judges Randy Jackson and Keith Urban tried to keep the peace. 

On Thursday, "The View" co-host Barbara Walters said she spoke to Carey who said multiple people heard Nicki say, "If I had a gun, I would shoot the b***h." 

According to Walters, Carey said she "doesn't feel comfortable emotionally" but will continue with the show and has hired extra security.

Walters said the judges had a meeting with producers on Wednesday to discuss the altercation and after the meeting, Minaj told Carey, "I love you but we might fight again." Carey rebutted saying "No, we will not," according to Walters.

Nicki took to Twitter to share her thoughts on the matter with her 14.5 million followers.

"Hey yAll. Lets just say nicki said smthn about a gun. ppl will believe it cuz she's a black rapper. Lmao. I'll then hit up Barbara n milk it," the rapper said on Twitter. 

According to Nicki, the producers did not believe Carey's claim about the gun threat and no camera or mic heard the gun comment.

Nicki bashed Walters for not reaching out to her team for her side of the story.

"I guess we're too dangerous," she said. "I don't call tmz n Barbara Walters cuz I stand on my own two feet. Never needed an army. God is good. Insecurity is as cruel as the grave."

Nicki said she thinks the tension is because producers supposedly told Carey that Nicki is the "best judge we've had since Simon."

Nicki said all she does is compliment Carey.

"That's not enuff? Ur a legend, cheer up. U don't have to run down ur resume or feel intimidated. Shady McGrady...," Nicki tweeted.

Urban spoke about the incident for the first time at last night's Paperboy premiere at the New York Film Festival with wife Nicole Kidman.

"I was the UN," the country singer told "Extra." "I love working with passionate people. I love artists. Everyone just sort of expressing themselves. It's a very alive and very invigorating work environment. A lot of passion."

Host Ryan Seacrest said he has no problem with the two ladies squaring off. 

"We want that," Seacrest said on his radio show after the incident. 

"We want them to be on this panel together. This is a good team, a great team, to go out and look for the next American Idol. [There's] nothing wrong with disagreeing ... That's gonna happen, and it's okay. These are all very different individuals with different perspectives and different opinions that provide for interesting conversation and dialogue and feedback for the contestants."

Carey's husband, Nick Cannon, said he feels like the bickering is taking away from the quality of what 'Idol' is all about. 

"This is about people accomplishing their dreams, experts guiding these young people to do what they've done," Cannon told "Access Hollywood" Wednesday.

Cannon said he does not think that Carey is moved by the theatrics and pageantry of the show.

"My wife is the strongest and classiest woman that I've ever met," he said. "If you watch the video, she just maintains her composure. She signed up to do a job to help young people, this is like a sidebar. I hope that's not what this show becomes, about the cat fights.
