One of Truman Capote's closest confidantes has revealed the writer captured footage of a secret meeting between Jackie Kennedy and Marilyn Monroe at his home in New York just weeks before the actress' death in 1962.

Celebrity seer John Cohan tells WENN Capote showed him the footage of the tense showdown between President John F. Kennedy's wife and his alleged mistress, which he filmed without the two women's knowledge, multiple times before he sold the home video to Tv mogul Merv Griffin in the eraly 1980s.

Griffin, in turn, had planned to release the film on the 50th anniversary of Monroe's death last year (12), but died in 2007 before he could create the television special he had planned.

Now Cohan has no idea what has become of the footage, but he's convinced it will be broadcast in the near future.

He says, "I was reminded of this film while I was recalling my friendship with Truman for a new book, titled The Pink Triangle.

"Truman had been a friend to Jackie Kennedy but they had a falling out and when she asked him to arrange a meeting with Marilyn at his home, he bugged the room and filmed them. He did this because he could be devious and cunning."

And Cohan was stunned when the author first showed him the footage.

He recalls, "I remember Marilyn arrived looking like the movie star she was, dressed in a stunning white dress and Jackie showed up in this very tailored black suit, which made her look very matronly... When Mm (Marilyn) first started the greetings, she said, 'Hello Madam Jacqueline'.

"The two women were together a little over 30 minutes and Jackie basically told Marilyn she knew what was going on between her husband and Marilyn, and wanted it to stop. Jackie said she forgave Mm for the affair with her husband because she knew too well Jack could charm a dead body and get a response.

"Marilyn became hysterical because she didn't want to end the affair. Money was exchanged. Jackie had with her a good size pink round hat box. In it was a lot of money. She said to Mm, 'Take this and use it to make your new home more beautiful and the rest invest in stocks and other good ventures for your future'. By the end of the film, Marilyn was a mess. Her hair was all messed up and her mascara was running."

Cohan admits Capote was very guarded about the film and, as far as he knows, he's the only person who has seen it other than the author and Merv Griffin.

He adds, "In the beginning, Truman kept it because he wanted to get back at Jackie and just by having this film he felt he had achieved that, but over the years he got so bored with it and told me, 'I'm going to sell it' - and he did.

"Merv Griffin treasured the footage and intended to keep it under lock and key until the 50th anniversary of Marilyn's death. Like Truman, he was very guarded about this and I don't think he showed it to anyone or talked about it.

"Unfortunately Merv, another great friend of mine, died before his time and the footage is now lost, but I'm sure Merv took care of all his affairs before his death and had plans for this film. I'm sure it will see the light of day at some point."
