7. John and Jacqueline Kennedy
Another apparently political marriage, these two seem to have spent much of their time attempting to get back at one another through having multiple affairs. The strange truth is that while this couple was presented to the public as the perfect All-American brand, it appears that there could be nothing further from the truth. Each is rumored to have had affairs with prominent celebrities. In 1957, due to frustration with their marriage, John sent Jackie to a clinic in Massachusetts where Jacqueline was subjected to 3 electroshock treatments, which were so barbaric that Jackie contemplated suicide afterwards. After JFK’s death, Jackie is believed to have had affairs with both Bobby and Ted Kennedy.
