It appears that video footage of a sexual encounter between Marilyn Monroe and brothers John F. Kennedy and Robert F. Kennedy not only exists, but will be put up for auction on Tuesday, according to numerous online reports.

According to radaronline.com, the never-seen-before footage was acquired by former bodyguard William Castleberry, who was a collector of Hollywood memorabilia.

Castleberry said he never released the video out of respect for Joe DiMaggio, who married Monroe in 1954.

Castleberry, who did not reveal how he got his hands on the video, had it seized by authorities in California after a lawsuit accused him of selling a fake statue.

Because Castleberry couldn't pay the $200,000 he owed in the judgment against him, officials are reportedly set to go ahead with the auction -- unless Castleberry can come up with $200,000.

Social media reacted with surprise, sarcasm, and, of course, curiosity.
