"Which wife of a top Lehman executive went on a $132,000 shopping spree at the Americana Manhasset Mall the day after her hubby filed for bankruptcy?" Page Six asked today. It didn't take very long for commenters over at Dealbreaker to come to a conclusion. After eliminating Dick Fuld's wife Kathy (who spends most of her time in Greenwich and wouldn't be caught dead shopping at a Long Island mall), the crowd seemed to settle on Niki Gregory, the wife of axed Lehman president Joe Gregory, who has a home in nearby Lloyd Harbor and was rumored to be filing for personal bankruptcy in September.
