The opposite sex (1956)

Shortly after their 10th wedding anniversary, New York City theater producer Steven Hilliard (Leslie Nielsen) and his wife, former popular radio singer Kay Ashley Hilliard (June Allyson), are getting a Kay-initiated Reno divorce after Kay finds out about a marital indiscretion he had with Crystal Allen (Dame Joan Collins), a gold-digging chorus girl in one of his shows. News of the indiscretion made its way to Kay indirectly by her catty friend Sylvia Fowler (Dolores Gray). In getting the divorce, Kay's best friend, playwright Amanda Penrose (Ann Sheridan), believes Kay is playing right into the wants of Crystal, whose main goal is not to be happily married to Steven, but to get what such a marriage can bring her in material wealth and comfort. Amanda does not believe Steven loves Crystal and that he still really loves Kay. Kay proceeds with the divorce despite believing they'd had a happy, loving marriage before she learned of the indiscretion, and despite having adolescent daughter Debbie (Sandy Descher) to consider. But when Kay learns information of the goings-on within her social circle, she decides to take back control of her married status while exacting some revenge.
