Jackie Kennedy Book Reveals Shared Therapist with Marilyn Monroe

The surprising connection between Marilyn Monroe and Jacqueline Kennedy Onassis has been detailed in a new biography titled “Jackie: Public, Private, Secret” by J. Randy Taraborrelli.

The book, exclusively excerpted in this week's issue of PEOPLE, sheds light on Jackie's therapy sessions with psychoanalyst Dr. Marianne Kris in the 1970s, during her tumultuous marriage to Aristotle Onassis.

Taraborrelli's research uncovered that while Jackie was in therapy, she discovered that Dr. Kris had once treated Monroe.

Patricia Atwood, Kris' former secretary from 1972 to 1974, shared in an email, “Dr. Kris would never discuss Mrs. Onassis, citing doctor-patient confidentiality.”

However, notes from the therapist revealed some insights into Jackie's sessions.

The therapy sessions addressed Jackie's ongoing post-traumatic stress disorder (PTSD) following the assassination of President John F. Kennedy, as well as her concerns about their marriage.

According to Atwood, one of the notes read, “He went out in a blaze of glory, Mrs. Onassis said.

The way he died had completely robbed her of the right to hate him.”

During these sessions, Jackie learned about Dr. Kris' previous treatment of Monroe, who was rumored to have had an affair with JFK.

Taraborrelli quotes Jackie confronting Dr. Kris, who responded by questioning the relevance of the information.

Jackie's retort was, “How is that not relevant?”

Rumors of Monroe's alleged affair with JFK were fueled by her sultry performance of “Happy Birthday” at his 45th birthday celebration in 1962, just months before her death.

Over the years, accounts of Monroe's relationships with both JFK and his brother, Robert F. Kennedy, have been extensively explored in various media.

Monroe biographer Jason Spada previously stated that JFK had passed Monroe onto his brother after growing tired of their romance.

Spada noted that it was evident Monroe had been involved with both Jack and Bobby.

It has been nearly six decades since Jackie was with her husband during the fateful motorcade in Dallas when he was assassinated on November 22, 1963.

She went on to marry Aristotle Onassis in 1968 and later found companionship with Maurice Tempelsman, a diamond merchant.

In early 1994, Jackie was diagnosed with non-Hodgkin lymphoma and passed away on May 19 of the same year.

Throughout her life, she maintained a private stance on her personal affairs, including her relationships and therapy sessions.
