Squires met the actor Roger Moore at one of her parties at her mansion in Old Bexley, Kent. Moore, who was 12 years her junior, later became her husband when they married in New Jersey on 6 July 1953. She later said, "it started with a squabble, then he carried me off to bed." She introduced him to various people in the Hollywood film industry. As his career took off, hers started to slide. Their marriage lasted until 1961, when Moore left her. He was unable to marry legally until Squires agreed to a divorce in 1969 – the day on which Squires was convicted of drunk driving.
