James Van Der Beek and Kimberly Brook have welcomed their first son.
The Dawson's Creek actor - who already has 18-month-old daughter Olivia with Kimberly, his second wife - revealed the news on Twitter, but has yet to reveal a name for the newborn.
He wrote: "Had my first son this morning... well, actually, my wife had him. I just caught him. Wow. Heart expanding way faster than my brain...
"If you could bottle up and distribute this feeling, I swear there'd be no more war. #fatherhood(sic)"
James - who starred alongside Katie Holmes and Michelle Williams in Dawson's Creek - regularly tweets about his family life on Twitter, and previously claimed his daughter was growing up particularly fast.
