The 'Til Death star and her husband, cinematographer Christopher Duddy, have just welcomed their third child together.
Fisher, 40, and Duddy adopted a newborn girl, Olivia Luna Fisher-Duddy, the actress tells E! News.
The baby weighed 7 1/2 pounds and measured 19 1/2 inches at birth; the couple has declined to release details of the child's biological mother.
Olivia joins sisters Sklyer, 7, and True, 2, in the Fisher-Duddy brood.
The couple also have two adult sons, Cameron, 22, and Collin, 20, from Duddy's first marriage.
Says Fisher's rep: "They are all blissfully happy and enjoying their new baby sister."
