Starting in the mid-1970s, Joanne was showcased less on the program. She became rivals with Stephanie Wilkins, who had an affair with her third husband, Tony, and later married John Wyatt, her former brother-in-law, out of spite. Joanne's final stories involved her romance with Martin Tourneur (John Aniston), whom she married in 1980. They later divorced, which was considered a scandal because it was Joanne's first divorce. Mary Stuart confessed that because she had divorced him because of his infidelity, she laughingly considered herself the "world's oldest ingenue".
