Parker remained active in film throughout the war, playing opposite Lon Chaney Jr. in the film noir thriller Dead Man's Eyes (1944). For Monogram Pictures, she inaugurated the Kitty O'Day mystery film series, playing the title character in two films: Detective Kitty O'Day (1944), and Adventures of Kitty O'Day (1945). In the latter part of the 1940s, Parker appeared in several stage productions: She made her Broadway debut in the title role of the comedy Loco in 1946. Journalist Lee Evans of The Cincinnati Enquirer gave the play a middling review, noting that while the play was "fairly well acted," Parker "does not create any great stir with her performance." Parker returned to Broadway with a starring role opposite Bert Lahr in Burlesque (1946–1947). In late 1948, she replaced Judy Holliday in the national touring Broadway production of Born Yesterday, co-starring with Lon Chaney, Jr. Her performance in the production was well received by audiences. A review of the October 1948 Philadelphia premiere by The Philadelphia Inquirer gave the production a rave review, noting: "To say that piquant and personable Miss Parker, and Chaney as her uncouth, comedy Caliban, play their parts as though they had been written for them, is the highest possible praise, but is amply merited for the zestful spontaneity of their performances." In the summer of 1949, Parker appeared in a production of the comedy play Light Up the Sky, opposite Gregory Peck, which opened at the La Jolla Playhouse before having touring performances throughout the fall of that year. On December 29, 1949, Parker and her third husband, Grotter, were granted a divorced following their July 1949 separation.

Also in 1950, Parker returned to film with a supporting role in The Gunfighter opposite Gregory Peck, playing a saloon singer. The following year, in 1951, while appearing at a nightclub in Sydney, Australia, Parker made international headlines when she was escorted off Bondi Beach by swimsuit inspector Abe Laidlaw, who measured her bikini and determined it was too skimpy. On May 19, 1951, Parker secretly married actor Robert Lowery Hanks at the home of a friend in Hialeah, Florida. The
