Open Marriages: Hollywood’s Worst Kept Secret?
John F. Kennedy and Jackie Kennedy

This couple should come as no shock considering the infamous affair that existed between former President John F. Kennedy and the insatiable Marilyn Monroe. Rumors of Jackie’s knowledge of the two never quite cleared over the years; some say that she was about to divorce John right before his assassination and others say that the two practiced an open marriage that allowed Kennedy to get frisky with the iconic and beautiful movie star and others.
Married, what seemed to be happily, for almost exactly a decade before the tragedy occurred, many people in the public believed that the couple had arranged an open marriage for the President’s straying eye. But, we can never truly be sure.
