The untold story of the rivalry between America’s most famous first lady, Jackie Kennedy Onassis, and her sister, Lee Radziwill, is being told in a new book. In ‘Jackie, Janet, and Lee,’ best-selling biographer J. Randy Taraborrelli says the sisters’ lifelong competition was sparked by their controlling mother, Janet Lee Auchincloss. “When Jackie died, much to Lee’s surprise, she left her no money at all,” he said. “But Janet really did not want them to compete with one another.”
