Congrats are in order for former ER star Kellie Martin and her husband, Keith Christian, as the actress gave birth to a baby girl on Feb. 18.

ET Online noted that this is the second child for Martin and Christian. They also have a 9-year-old daughter, Margaret Heather.

People reported that the couple named the new baby Olivia James Christian and she weighed in at 7 lbs., 15 oz. and was 20 inches long.

After Olivia met her big sis, Martin shared a sweet pic of both her daughters via Instagram and simply captioned it, “She’s finally here.”

The 40-year-old first announced her pregnancy last September when she was already five months along and said that Maggie took the news of having a sibling very well.
