They met on the filming of "Some Like It Hot" in 1958. They had an affair although he was married to Janet Leigh at the time, and she was also married, to Arthur Miller. "When I was in bed with Marilyn I was never sure - before, during or after - where her mind was," he wrote. "She was an actress. She could play a part. She could give the part what she thought a man wanted. I never asked for more." He even claimed she got pregnant with him, but unfortunatelly she miscarried.
