Nicki Minaj is said to have threatened Mariah Carey after her American Idol co-star called her a 'b****' - it is now being claimed.
Show bosses cancelled filming in Charlotte, North Carolina for the day on Tuesday after a huge blow up between the pair where Nicki allegedly threatened and swore at Mariah.
But witnesses insist Hero hitmaker Mariah started it, according to reports.
'Nicki Minaj walked off of set because Mariah Carey kept making jabs at her.
'Nicki’s manager and team convinced her to come back to the show. Mariah kept at it and called Nicki "a b****" and then proceeded to cuss her out. Producers had to stop filming and call it a night.'
It was previously reported how Nicki fumed she was sick of her co-judge, labelling Mariah her 'f*****g highness'.
Mariah was said to be unhappy with Nicki joining American Idol because she was worried it would turn the reality TV programme into a 'freak show'.
During their first taping of the talent reality show the pair were said to have talked over one other in a bid to be the most vocal judge.
The drama began when 29-year-old Super Bass singer Nicki starting critiquing a contestant, but despite it being her moment to be in power, Mariah, 42, couldn't resist butting in on several occasions.
