After a Nicki Minaj aand Mariah Carey had a major blow out during the 'Idol' auditions last October, Mariah admitted that she hired extra security because she felt unsafe after the 'Starships' singer made her feel threatened. But now, Nicki softened her tune. She told 'Us Weekly', "I say nice things about Mariah all the time. She's one of my favorite artists of all times." We will have to watch their relationship evolve or devolve, when'American Idol' season 12 premieres on Fox, on January 16th.
