Mariah Carey has reportedly called in the help of extra bodyguards after Nicki Minaj apparently made threats to her on American Idol.
Things started to get out of control when the pair was arguing over a contestant, with third judge Keith Urban left stuck sitting literally in the middle of the pair as he tried to calm the situation down.
It was claimed that Nicki made comments to production staff stating that if she had a gun she would shoot Mariah.
The situation got fired up further when Mariah's pal Barbara Walters said on TV that Mariah was trying to protect her twins and felt that the Starships singer's behaviour was "unpredictable".
However, Nicki was quick to hit back at Mariah on her Twitter, stating that despite the number of cameras and microphones on the pair at the time, there was no evidence that she made the comment.
She added: "I guess it hurts to have the producers tell you to your face that Nicki is the best judge we've had since Simon."
Ouch - hopefully the pair can get over their spat and get back to the task at hand of picking finalists for the latest series of the talent show.Suggest a correction
