Joely Fisher and her husband have four other children

It's a party of five for Joely Fisher's brood.

The "'Til Death" actress and her husband Christopher Duddy have adopted a newborn baby girl, reports People.

Olivia Luna Fisher-Duddy weighed 7 1/2 lbs. at birth. The Fisher-Duddy family already has four kids: sons Cameron, 22, and Collin, 20, and daughters Skylar, 7, and True, 2.

"They are all blissfully happy and enjoying their new baby sister," says Fisher's rep, Brit Reece.

Out of respect for the birth mother, no other details are available.

Fisher, 40, stars opposite Brad Garrett in FOX's sitcom "'Til Death," which premiered its third season earlier this month.
