Marilyn Monroe entered the history of cinema in the incredible film Some Like It Hot in 1959, but behind the scenes during the filming of the film she was indulging in a secret affair with the actor who shared the film with her, Tony Curtis, the relationship ended her secret pregnancy.

And it ended with the intervention of her husband after knowing the subject.
Marilyn met Tony Curtis and began an affair with him in 1949. He wrote of her in his autobiography: “When in bed with Marilyn, I was never sure, before, during or after the relationship, where her mind was. . She was an actress. She could play a part. She can play the part I thought a man would want. I never asked for more.”
They once became close during the filming of Some Like It Hot, and although they were both married, they had an affair that ended when Marilyn told Tony Curtis and his husband, Arthur Miller, that she was pregnant by Tony Curtis. Later, her husband asked Tony Curtis to get out of his life and he did, but added in his memories that he knew that Marilyn had a miscarriage at that time.
