Pop beauty Mariah Carey allegedly dined with a New York gangster during her marriage to ex-husband Tommy Mottola, a former FBI agent claims. JOAQUIN MANUEL GARCIA, who retired from the FBI in March (06), made the revelations as he testified in alleged mob boss GREG DE PALMA's racketeering trial in a Manhattan court room on Monday (15MAY06). Garcia claims De Palma, 74, brought him into the mob and he secretly recorded conversations during his time with the criminal gang. During a recorded conversation, De Palma claims he enjoyed a series of dinners with the singer and her music mogul husband in the mid-1990s. De Palma described Carey as "very nice, very quiet, reserved". When asked for comment by the New York Daily News, a spokesman for Mottola denied he had spent time with De Palma.
