James Van Der Beek is about to be a dad… AGAIN! The actor revealed on Friday that he and his wife, Kimberly, are expecting their fifth child.

Van Der Beek — who is currently filming Ryan Murphy’s new FX series Pose — made the big announcement on Instagram, posting a pic of his four beautiful children surrounding their mom, who is seen resting on a bed while showing off her growing baby bump. While the three girls put their hands on their mama’s tummy, Van Der Beek’s son flashes a sweet smile at the camera.

The 40-year-old former Dawson’s Creek star added the caption, “Thrilled beyond belief to announce that we are once again adding to our family 😍.” He hilariously added, “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

James and Kimberly Van Der Beek have been married since 2010 and are already the proud parents of seven-year-old Olivia, five-year-old Joshua, four-year-old Annabel Leah, and one-year-old Emilia. And while that might seem like a full house, it sounds (and looks) like this brood is ready to welcome (at least) one more smiling face into their home.

Congratulations to the excited family!

Do you (or would you) have five or more kids? Let us know @BritandCo!
