Dawson’s going to be a daddy!

James Van Der Beek and girlfriend Kimberly Brook are expecting their first child this fall, the actor’s rep has confirmed.

“Yes, it’s true – the woman I love and I are expecting our first child,” Van Der Beek, 33, Tweeted. “Currently experiencing joy on levels I never knew existed.”

Former Dawson’s Creek star Van Der Beek — who’s currently appearing on NBC’s Mercy — and Brook, a business consultant, met last July after the actor split from ex-wife Heather Ann McComb in April 2009.

The ex-couple reached a divorce settlement last month.
