Shirley MacLaine claimed that she had affairs with all of her leading men except for Jack Nicholson and Jack Lemmon. MacLaine was in a 28-year open marriage.

One leading man that she certainly didn't have a relationship with might surprise fans, due to his own high profile love life. Shirley claimed that the only two leading men she didn't fall in love with were Jack Lemmon, who she said was "like a sister to me," and Jack Nicholson. She famously worked with the latter on Terms of Endearment.

Shirley MacLaine has revealed she once hit on Morgan Freeman but he turned her down. In her new book, The Wall of Life: Pictures and Stories from This Marvelous Lifetime, the veteran actress revealed that she had a romantic interest in Freeman but her feelings were not reciprocated.
