An unreleased and well-concealed sex tape starring Marilyn Monroe was recently unearthed and sold for $1.5 million to an unknown businessman, the NY Post is reporting. Clocking in at 15 minutes, the footage shows a "radiant" Marilyn on her knees before an unidentified man performing oral sex. Previously released to the FBI in the mid-1960s, then-FBI director J. Edgar Hoover reportedly spent hours watching the footage in an attempt to prove that the receiver of the fellatio was indeed JFK (because, you know, that's why most people watch pornographic tapes for hours: work-related purposes). However, the Post also documents attempts by baseball star Joe DiMaggio to bury the tape by purchasing it for $25,000. The owner of the tape turned it over to government authorities, but not before making a single copy, which has now been tracked down and purchased by a mysterious businessman in an effort to bury it further so as not to soil the reputation of America's most famous dead blonde bombshell. "He said, 'I'm not going to make a Paris Hilton out of her. I'm not going to sell it, out of respect.' "
