Marilyn and Yves Montand
During the filming of Let’s Make Love, Marilyn Monroe and Yves Montand, the film’s stars, had a public affair which drew the attention of gossip columnists in America and France. Montand was married at the time to Simone Signoret, Marilyn to Arthur Miller. The affair ended with the completion of filming, with Montand publicly addressing the story with reporters. “Had Marilyn been more sophisticated, none of this ever would have happened”, Montand told reporters, adding “But, nothing will break up my marriage”.
Marilyn attempted to get back in touch with the French actor during the filming of The Misfits, evidently to no avail. Montand remained married to Simone Signoret until her death in 1985. Monroe, as noted, moved on to divorce Arthur Miller and did not remarry. Montand was but one of several extramarital affairs she had throughout her lifetime.
