Nicki Minaj and Mariah Carey engaged in a diva lockdown on American Idol last month. But now Minaj has turned her attention to talk show host Barbara Walters who called the rapper’s behaviour “unpredictable” on The View this week. This tepid diss apparently sent Minaj into a tailspin who took to an E! special to lay the smackdown on Walters. Said Minaj, “”Am I not good enough for you to get my side because I’m a little black girl that raps? . . . If I was J. Lo, you woulda called J. Lo’s camp,” she said in reference to Jennifer Lopez, who was a previous Idol host. ”I’m only good enough for you to tell people that I’m unpredictable when you don’t f**king know me!” Walters then rebuffed ensuing tweets by Minaj with accusations that she didn’t want her on her show, saying that they had indeed reached out. The only way to rectify this is obviously a rap battle between the two of them, right?
