Collins's wife, Victoria Vantoch, gave birth to a little girl, according to an announcement from the show's Twitter feed. Further details were not released.
Last weekend, Collins canceled a scheduled fan meet-and-greet appearance at Creation's Salute to Supernatural Convention in Dallas because he was "awaiting the imminent birth of his new baby," according to a statement from organizers, as reported by Zap2it.
This is the second child for the couple, who were married in 2002. Their new addition joins big brother West Anaximander Collins, 2.
