NEW YORK: Mariah Carey is going to be replaced by Jennifer Lopez on American Idol. According to a new report, Carey - who was ballyhooed as hot addition to the flagging American Idol last season - responded with legal threats from her lawyers when she learned she was marked for banishment. While Carey’s litigious threat put the kibosh on that potential setback, Idol’s producers are said to still be looking for a replacement for her and possibly Nicki Minaj as well as that combustible chemistry experiment was Minaj’s volatility. Idol producers are still negotiating with the ever-popular “Jenny from the Block” to appear on the Idol season finale in an effort to drive viewership numbers up.–SS
