Hollywood legend Marilyn Monroe made headlines after singing ‘Happy Birthday’ to former President of the United States, John F. Kennedy. Ever since, there have been rumors that Monroe had an affair with the late President and his brother Bobby Kennedy, who served as the 64th United States Attorney General from January 1961 to September 1964, and as a US Senator from New York from January 1965 until his assassination in June 1968. Marilyn’s biographer James Spada once told People: “It was pretty clear that Marilyn had had sexual relations with both Bobby and Jack.” According to Spada, Monroe met JFK in 1954, but when he got tired of the actress, he “passed her off” to his brother.
