The Dawson's Creek star shared on Instagram on Friday that his wife, Kimberly, is pregnant with baby No. 5, in a sweet pic of all the Van Der Beek kids -- 7-year-old Olivia, 5-year-old Joshua, 4-year-old Annabel and 1-year-old Emilia, gathered around Mommy's baby bump.
"Thrilled beyond belief to announce that we are once again adding to our family," the 40-year-old actor shared on Twitter, joking, "And I say 'beyond belief' because some people are probably wondering if we’re out of our minds. Which we might very well be... but I couldn’t be more excited. Or grateful. Or in awe of @vanderkimberly."
