Marilyn Monroe's JFK phone call haunted Jackie Kennedy years after star's death, author claims

Jackie Kennedy, who was married to President John F. Kennedy and Greek shipping magnate Aristotle Onassis, died in 1994 at age 64. She is the subject of a new book.

Author J. Randy Taraborrelli told Fox News Digital that the glamorous wife of President John F. Kennedy thought it was a cruel practical joke. His book, "Jackie: Public, Private, Secret," published on Tuesday, is based on nearly 25 years of research and hundreds of interviews with friends, family and lovers. It also references unreleased papers from the JFK Library, including diaries and oral histories. Stephanie Nolasco covers entertainment at Foxnews.com.

"There was something about that phone call," he explained. "She later told family members that there was a haunting quality to Marilyn’s voice that really stuck with her… And it’s not like they even had any kind of deep conversation… But it was 10 years of wondering, was it really Marilyn Monroe? And that buzz stayed with the family."

According to Taraborrelli’s book Monroe asked, "Is Jack home?" Kennedy said he wasn’t and then asked who was calling. "Marilyn Monroe," the caller replied. "Is this Jackie?" When Kennedy said it was, Monroe asked if she’d tell the president that she called. Kennedy asked what it was regarding, and Monroe said it was nothing in particular. She just wanted to say hello. Kennedy, still stunned, said she would pass on the message and hung up.
