In 1951, he married
Simone Signoret, and they co-starred in several films throughout their careers. The marriage was, by all accounts, fairly harmonious, lasting until her death in 1985, although Montand had a number of well-publicised affairs, notably with American actress
Marilyn Monroe, with whom he starred in one of her final films, ''
Let's Make Love''. He was the stepfather to Signoret's daughter from her previous marriage,
Catherine Allégret. Montand's only child, a son named Valentine by his second wife, Carole Amiel (b. 1960), was born in 1988. In a paternity suit that caused commotion across France, another woman accused Montand of being the father of her daughter and went to court to obtain a
DNA sample from him. Montand refused, but the woman persisted even after his death. In a court ruling that made international headlines, the woman won the right to have Montand exhumed and a sample taken. The results indicated that he was not the girl's biological father. He supported left-wing causes during the 1950s and 1960s, and attended
Communist festivals and meetings. By the mid-1980s his views had shifted to the right, and he became a spokesman for many rightist causes. Signoret and Montand had a home in
Autheuil-Authouillet, Normandy, where the main village street is named after him. In his later years, he maintained a home in
Saint-Paul-de-Vence, Provence, until his death from a heart attack in November 1991. In an interview,
Jean-Jacques Beineix said, "[H]e died on the set [of
IP5: The Island of Pachyderms]... On the very last day, after his very last shot. It was the very last night and we were doing retakes. He finished what he was doing and then he just died. And the film tells the story of an old man who dies from a heart attack, which is the same thing that happened!" Montand is interred next to his first wife,
Simone Signoret, in
Père Lachaise Cemetery in Paris. In 2004, Catherine Allégret, Signoret's daughter from her first marriage to director
Yves Allégret, alleged in her autobiography ''Un monde a l'envers
(A World Upside Down'') that she had been sexually abused by her stepfather from the age of five; his behaviour apparently continued for many years and he had a "more than equivocal attitude to her" as she got older. However, she also claimed to have reconciled with him in the latter years of his life. ==Filmography==
