Nicki Minaj ruffled more than just Mariah Carey's feathers on last night's episode of American Idol.

The outspoken spoken pop singer and rapper was harshly critiqued when she appeared on the show wearing a skin tight ruby red dress which flaunted a healthy dose of her cleavage. As a result, critics slammed the dress as being too provocative for a family oriented show that attracts young viewers on Twitter.

In addition to her look, the "Super Bass" singer was also criticized when she told fellow judge Mariah Carey to "simmer down, sir."

The two women clashed following contestant Kree Harrison's performance, fueling their ongoing feud that started at the beginning of the season.

"I disagree... that was the best performance of the night," Minaj told Carey after she had criticized the performance.

"I wasn't saying she was awkward... you don't really disagree with me," responded Mariah.

Minaj responded, "No, I do and I'll explain."

Carey then tried to interject again, but Minaj sharply told her to "Simmer down sir!"

The recent spat comes as ratings for the latest series of American Idol were announced as being the lowest in over a decaded, according to Forbes and The New York Daily News.

Nigel Lythgoe, the "American Idol" executive producer, said that a feud between Carey and Minaj in the beginning of the season may have hurt the show's chances during season 12.
