Shirley MacLaine Explains Her 28-Year Open Marriage

"I think that's the basis for a long-lasting marriage," she says.

"No one understood it, we did. He lived in Japan basically, I lived in America working, and this and that," she told People magazine of her time with producer Steve Parker before the two split in 1982.

He died in 2001. "We'd meet up, always great friends, traveled sometimes together," she said.

She added, "I guess you would say 'practiced an open marriage' in 1954, which was another lifetime."

MacLaine was adamant that being open is why her marriage lasted so long.

"I think that's the basis for a long-lasting marriage, if you really want to do such a thing," she said. "I would say better to stay friends and we don't have enough time to talk about the sexuality of all. I was very open about all of that and so was he."
