Bouvier Kennedy, died two days after birth in August 1963. Affairs and friendships Kennedy was single in the 1940s while having relationships with Danish journalist Inga Arvad and actress Gene Tierney. During his time as a senator, he had an affair with Gunilla von Post, who later wrote that the future president tried to end his marriage to be with her before having any children with his wife. Kennedy was also reported to have had affairs with Marilyn Monroe, Judith Campbell, Mary Pinchot Meyer, Marlene Dietrich, Mimi Alford, and his wife's press secretary, Pamela Turnure. The full extent of Kennedy's relationship with Monroe (who in 1962 famously sang "Happy Birthday, Mr. President" at Kennedy's birthday celebration) is not known, though it has been reported that they spent a weekend together in March 1962 while he was staying at Bing Crosby's house.
