The Dawson's Creek star and wife Kimberly welcomed a baby daughter at home on Saturday, 25 January.
James confirmed the news via Twitter, writing: "Outnumbered by kids, outnumbered by girls, outlandishly grateful and thrilled... Watch out world, VDB baby #3 made her debut last night :)"
No further details including the baby's name have been released yet.
James, 36, and Kimberly are already parents to daughter Olivia, three, and son Joshua, who is nearly two.
The couple announced their third pregnancy via Kimberly's blog in August 2013, with her writing: "All of the craziness, exhaustion and moodiness aside, James and I are beyond elated and feeling so incredibly blessed."
"Olivia and Joshua are in on the news and seem to be excited about a baby coming into the family," wrote Kimberly. " And James, thank you for being the loving, caring and understanding husband and father that you are."
Congrats to James and Kimberly!
