Dawson’s a dad -- again!

James Van Der Beek and his wife Kimberly Brook welcomed their second child -- a son -- into the world on Tuesday, and in true celeb style, the Dawson’s Creek star announced the happy news via Twitter.

“Had my first son this morning… well, actually, my wife had him. I just caught him. Wow. Heart expanding way faster than my brain,” Van Der Beek, 35, wrote.

“If you could bottle up and distribute this feeling, I swear there’d be no more war. #fatherhood”

The couple -- who married in August of 2010 after he divorced his first wife Heather McComb -- also has a 17-month old daughter, Olivia.

Last October, Van Der Beek announced -- also via Twitter -- that he and Kimberly were expecting again.

At that time, he wrote: "Just when we thought we couldn't feel any more blessed, it seems the universe has plans to give our daughter a sibling... #humbled (sic)."
