(16 March 1968 - 21 January 2000) (his death)
Her second husband was Texas oilman Tom Gallagher, to whom she was wed from 1968 until his death from lung cancer on January 21, 2000. She suffered a miscarriage during her marriage to Gallagher, and the couple was childless. Asked about children in an October 2000 interview, Pleshette stated: "I certainly would have liked to have had Tommy’s children. But my nurturing instincts are fulfilled in other ways. I have a large extended family; I'm the mother on every set. So if this is my particular karma, that's fine."
