Radziwill, who died on Feb. 15 at the age 85, had a complex relationship with Jackie O. “The relationship was close yet threaded with rivalry and competition,” according to the book The Fabulous Bouvier Sisters: The Tragic and Glamorous Lives of Jackie and Lee.
The books authors claimed Radziwill once slept with her sibling’s first husband, John F. Kennedy.
“There were times when…I think Lee went perhaps too far. Like going to bed with Jack in the room next to mine in the south of France and then…boasting about it,” Lee’s first husband, Michael Canfield, once told the late writer Gore Vidal.
Kennedy Onassis was able to get revenge on her sister — by stealing Radziwill’s lover, Greek shipping tycoon Aristotle Onassis.
“This was a blow from which their relationship would never recover,” said The Fabulous Bouvier Sisters: The Tragic and Glamorous Lives of Jackie and Lee authors Sam Kashner and Nancy Schoenberger. “What made it more painful was that it was Lee who had brought Jackie and Ari together.”
The book also claimed the sisters’ mother, Janet, brought the pair “up like geishas, to get money out of men.”
Jackie O delivered a final blow to Radziwill when she passed away in 1994 at the age of 64 by leaving her younger sister with nothing in her last will and testimony.
