Shirley MacLaine opens up about her past sex life and "awful lot of lovers," saying she once "had three people in one day" and maintained an open marriage.
The actress, who will turn 77 on April 24, made her comments in a recent interview on "The Oprah Winfrey Show" to promote her new book, "I'm Over All That and Other Confessions." She writes that she has had relationships and romances with two prime ministers as well as scientists, journalists and her co-stars.
"I've had an awful lot of lovers," MacLaine said. "And a lot of awful lovers. I wasn't into sexcapades although I tried it once. Had three people in one day. It was on a political campaign where everybody was doing the same thing. Not my style at all. I was a serial monogamist and had many love affairs."
"But what happens when you get older and very rarely interested in the spiritual dimension of things, sex takes on a different meaning, a different importance, a different reason for being," she added.
MacLaine, sister of actor Warren Beatty, is known for movies such as "The Apartment" in 1960, "Terms of Endearment" in 1983 and "Steel Magnolias" with Dolly Parton and Julia Roberts in 1989.
In 1954, she married producer Steve Parker. The two had a daughter, Sachi, and divorced in 1982.
"I had other affairs and so did he but we were very good friends," McLaine said. "I would never get married again. There's so much involved with marriage that is confining. I was having all these wonderful relationships - that's a good marriage, that's my kind of marriage. I loved the freedom and so did he but we were very, very good friends."
MacLaine, who has penned books such as "Sage-ing While Age-ing" and "Out on a Leash: Exploring the Nature of Reality and Love," is already thinking about her next literary project.
"You marry someone, you promise to love, honor and hopefully not obey but it's probably still in the ceremony, and then years later you find someone attractive," she told Oprah Winfrey. "I want to do a book on sex. I want to do a book on what happens to the promises and the monogamy of love in a marriage when you're attracted to someone else."
