NEW YORK — Pop diva Mariah Carey said she hired increased security following what she described as threats reportedly made against her by fellow “American Idol” (A.I.) judge Nicki Minaj, according to an interview on ABC News. Carey, 42, one of three new judges to join the A.I. panel for the hit talent show's new season on Jan. 16, told Barbara Walters in an interview airing on Monday, “it felt like an unsafe work environment.” — Reuters
