Superstar Mariah Carey is being sued by her former manager JERRY BLAIR, who claims the singer owes him money. Blair was employed as the president of Carey's Monar C Entertainment firm, but his contract was terminated after the release of her record-breaking comeback album The Emancipation Of Mimi in 2007. A source tells the New York Daily News, "Jerry stood by Mariah through her breakdown (in 2001). He believed in her when other people lost faith. "(After the success of Mimi) she wanted to distance herself from anybody who saw her in those dark times." Blair claims Carey owes him a percentage of her record and tour profits. The source adds, "She hasn't paid him in two years. He had to call in lawyers." Blair is now working with Carey's ex-husband, music mogul Tommy Mottola at his Casablanca Records label.
