Gregson Wagner gave birth to Clover Clementyne Watson late last week, according to People.
The couple said in a joint statement: "We are overwhelmed with love and joy at the birth of our daughter Clover Clementyne Watson."
Clover apparently weighed 7 lbs, 2 oz at the time of her birth.
Gregson Wagner and Watson first announced that they were expecting a baby in early May.
Watson notably played Dr Matt Camden on 7th Heaven and also starred in the short-lived series What About Brian?.
