If there were a holy grail of sex tapes, then this would be it. In 2008 the New York Post reported that there was a secret Marilyn Monroe sex tape, which had been sold to an anonymous businessman for £750,000 so that he could keep it, and the actress’ reputation safe.

The 15-minute sex tape was allegedly shot in the 1950s, before the Some Like It Hot star hit the big-time, and featured the original blonde bombshell giving an unidentified male a blow-job.

The video had not been in circulation before as the FBI had held the original while they tried to determine whether the unidentified male could be John F Kennedy or Robert F Kennedy.

The silent, black and white flick reportedly shows Monroe on her knees in front of a man whose face is just out of the shot. The film was found by Keya Morgan, who was making a Monroe documentary. “You see instantly that it’s Marilyn Monroe – she has the famous mole,” he said.

Morgan claimed the video’s buyer is just going to “lock it up” to save the deceased star’s blushes.

Some Like It Hot indeed.
