Nicki Minaj thinks Mariah Carey has "met her match" in her.

The "Starships" singer has admitted there is more than one diva on the judging panel of American Idol following her explosive bust-up with the star last month, during which she hurled profanities at Mariah. "I think Mariah met her match this time, and I don't think she was expecting to meet her match. I'm super nervous and anxious for the first day on American Idol. I'm still second guessing my decision. I'm probably going to be a hundred times guessing this decision because I'm human. It's a big job," she revealed, speaking in her new reality show My Truth.

The outspoken rapper was true to her word and proceeded to have a meltdown because her new stylist had misjudged her taste in clothes mere hours before the first day of auditions, and she branded all her options ugly. "I never have a look in mind. I know it when I see it. If you tell me to choose something when I'm anxious or nervous, then I'm going to find a problem with every single thing ...This is 911. Dee-saster," she raged.

The 29-year-old star still struggled to find her perfect look and rocked up late for her first day on the job to join Keith Urban, Randy Jackson and Mariah on the panel. "Am I going to be an hour late or two hours late? Do they know literally how embarrassing this is. That I am going to be late for my first day," she moaned.
