Nicki Minaj and Mariah Carey Make 'American Idol' Judging Debut [Video]

After months of salary negotiations, feuding, and drama, Nicki Minaj and Mariah Carey finally took their seats on the judging panel for the 12th season of “American Idol.” The dueling divas’ antics were caught on camera during the first round of auditions in New York. They teased one another, rolled their eyes, and shared laughs while trying to find the next superstar.

There were several highlights during Wednesday’s premiere including Nicki’s heartwarming speech to James Bae, who she dubbed the “Asian Bieber.” Mariah met many contestants who were also Lambs including Tenna Torres, who attended Camp Mariah when she was a child.

Blueberry farmer Sarah Restuccio impressed the judges with a country song, but she really shocked them when she busted out the lyrics to “Super Bass” as Nicki rapped along.

But it was Ben Gaisey who stole the show with his Michael Jackson “Thriller” costume. However, he wasn’t exactly able to thrill the judges with his talent. He serenaded the ladies, even throwing a pelvic thrust in Nicki’s direction.

Relive these moments and tune in for more of Mariah and Nicki tonight at 8/7c on FOX.
