James Van Der Beek and his wife Kimberly became parents to a baby boy yesterday.

The former Dawson's Creek star announced the happy news on his Twitter page.

The couple already have 17-month-old daughter Olivia and James was delighted to add a new bundle of joy to his family.

"Had my first son this morning," James , 35, gushed. "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."

James and Kimberly tied the knot in August 2010 and announced in October that were expecting again.

"Just when we thought we couldn't feel any more blessed, it seems the universe has plans to give our daughter a sibling," James wrote at the time.

The actor can next been seen playing an exaggerated version of himself in ABC comedy Don't Trust the B---- in Apartment 23. The show follows a New York party girl who causes trouble for her nave roommate and premieres on April 11.
