Sex Goddess Marilyn Monroe died heartbroken - just 15 days after having an abortion ordered by bobby Kennedy.
And the tragic film star was so deeply involved with both Bobby and his president-brother Jack, she didn't know which man was the father of her child.
Those are two of the bombshell revelations buried in hush-hush FBI files on the assassination of President Kennedy.
The JFK files will rock America when the government releases them to the public.
An FBI insider has already revealed: "Marilyn had an abortion on July 20, 1962, at Cedars of Lebanon Hospital.
"A couple of days later, she tried to get through to Bobby in Washington to tell him she had got rid of the problem, but he ducked her calls.
"Fifteen days after she had it done, Marilyn was dead of a drug overdose.
"She suffered complications and became deeply depressed. She simply decided to end her life".
J. Edgar hoover, the FBI director at the time, knew about the abortion and had information about it locked away in the agency's top secret files. This secret data was recently declassified by President George Bush. And here is what the insider says the files will show - if they are all released:
Bobby Kennedy, the United States attorney general, promised to divorce his wife, Ethel, and marry Marilyn.
Instead, he waited until she aborted the baby before cruelly dumping her.
Peter Lawford, the Kennedy's brother-in-law, gave Marilyn an alibi to help cover up her abortion.
Marilyn's phones were tapped by a member of the Los Angeles Police Department, who later tried to sell the tapes for $50,000!
Justice Department offcicials falsified Bobby Kennedy's travel log to cover up the presence in Los Angeles the day Marilyn died.
J. Edgar Hoover was so shocked by the sex antics of the Kennedy brothers he couldn't bring himself to talk about them, even to his closest associates. In fact, Hoover listened to tapes of red-hot conversations between Bobby and Marilyn.
"Hoover knew all about those tapes," says the source.
"He also knew the LA police chief had copies, and he did his best to get his hands on them before they could be used to damage Bobby.
"Hoover despised the Kenedy brothers, but he was a loyal bureaucrat who saw it as his duty to protect his bosses - the attorney general and his brother, the president.
"Bobby is heard on the tapes ordering Marilyn to have an abortion. She checked into Cedars of Lebanon hospital in LA and had it done on Friday, July 20, 1962.
"Peter Lawford covered for her by announcing she was with him and his wife at lake Tahoe." In the late 1960s, a group of businessmen sent an investigator to LA to track down the tapes, says Ralph de Toledano, author of JFK - The Man Who would be President.

"The investigator called me and said he found the policeman who had the tapes," Ralph de Toledano said. "He had listened to them and said they were dynamite. But the cop wanted $50,000 for them."
The businessmen never went through with the deal because Bobby was murdered a few days later, Ralph de Toledano explains.
But there was even more to the cover-up of Bobby's affair with Marilyn.
The weekend of her death, the Justice Department concocted an elaborate alibi for the attorney general, claiming he spent the weekend with his family and friends near San Francisco.
In fact, he was staying at the Beverly Hills Hotel that weekend, and a photocopy of his hotel bill - published in a book on Marilyn's death by the late Frank Capell - proves it.
"Bobby tried to conceal his presence by having his room charged to the National Insurance Association in Chicago." the source says.
"But it didn't work - the hotel put his name on the bill as the person using the room.
"All that information went into FBI files, and it shocked Hoover. But the closest he ever came to talking about the exploits of the Kennedy brothers was to refer to their 'sex things."
