Nicki Minaj may or may not  become a judge on “American Idol,” but we hear Mariah Carey is very pissed about it. According to TMZ, when producers informed Mariah Carey that Nicki was the top candidate she hung the phone up. We mentioned earlier that Nicki may join AI as a judge, stay tuned. But all this diva-tude already???….American Idol should just get Lil Mamma and solve the money issues and judge issues ………(seriously)
