James Van Der Beek and wife Kimberly welcome their first son
Van Der Beek announced the news on Twitter, writing, " Had my first son this morning... well, actually, my wife had him. I just caught him. Wow. Heart expanding way faster than my brain..."
He continued: "If you could bottle up and distribute this feeling, I swear there'd be no more war. #fatherhood."
The baby boy's name hasn't been announced yet, but he joins big sister Olivia, who is 17 months. The actor tweeted in Oct. 2011 when he announced his wife's second pregnancy, "Just when we thought we couldn't feel any more blessed, it seems the universe has plans to give our daughter a sibling... #humbled."
Van Der Beek stars as a fictionalized, sleazy version of himself on ABC's new sitcom "Don't Trust the B---- in Apt. 23," which premieres April 11.
