Things continue to heat up between “American Idol” judges Mariah Carey and Nicki Minaj, with new allegations that Mariah has tightened security because she’s scared of the head Barb following a blowout during auditions.

On Thursday’s “The View,” host Barbara Walters revealed that she had spoken with Mariah who said that she had hired extra security after Nicki allegedly said, “If I had a gun, I would shoot that bitch.”

“She said she is very concerned,” said Walters. “She doesn’t feel that anything would happen, but ‘Nicki is unpredictable’ and Mariah says she can’t take a chance and she has hired extra security. Nicki has not apologized, but they have since been together at meetings with producers and judges. There was a meeting yesterday morning. After the meeting, Nicki said to Mariah, ‘I love you, but we might fight again.’ Mariah responded, ‘No, we will not.'”

Walters continued recounting what Mariah told her. “At this point, Mariah said she doesn’t feel comfortable emotionally, but she will continue with the show because she loves the show and she loves mentoring the contestants.”

Nicki has since gone on a tweeting spree, refuting the allegations. Check out some of her tweets below.
