A rep for the actress confirmed to Us magazine that Russell and her husband, Shane Deary, welcomed the baby girl on Dec. 27. Their new daughter’s name: Willa Lou Deary.

The former “Felicity” star and her husband of nearly five years also have a 4-year-old son, River Russell Deary.

Russell — who has appeared in films such as “Waitress” and “Mission: Impossible III,” and most recently starred opposite Will Arnett in the Fox comedy “Running Wilde” — will next be seen in the films “Goats” (co-starring Vera Farmiga and David Duchovny) and “Austenland,” a rom-com about a “Pride and Prejudice”-obsessed woman who goes to a Jane Austen-themed resort.
