Lee Radziwill, Jackie Kennedy Onassis’ younger sister, died Friday in New York at age 85, according to Women’s Wear Daily. Radziwill, whose careers included acting, interior design, and public relations, as well as coordinating special events for Giorgio Armani, was born Caroline Lee Bouvier. She became a princess after marrying Polish prince Stanislaw Albrecht Radziwill in 1959. While Radziwill had previously suffered from age-related illness, sources told WWD that she had appeared healthy this week. Radziwill’s friends included author Truman Capote, who helped launch her acting career. She also counted Cecil Beaton and Leonard Bernstein among her confidants. She was so close to Andy Warhol that she leased his Montauk property from him after leaving Radziwill, WWD notes. In 1972, she traveled with the Rolling Stones’ tour in North America. Radziwill’s high-profile and luxe life was coupled with financial difficulties. Onassis didn’t leave Radziwill any money from her $150 million estate, even suggesting in her will that she had helped support her younger sister, per WWD.
