It's a triple birthday, shared by Selleck, her maternal grandmother and now Selleck's new baby girl.
Sarah Victoria Selleck arrived a bit early. Selleck's due date was toward the end of the month, but she went into labor after getting a check-up.
Hospital officials say this is the first child for Selleck and her husband, Aaron Selleck, of Beaverton, Oregon.
Mom, dad and their 6-pound, 6-ounce girl are all doing fine.
