Just days after honoring their one-year wedding anniversary, Colton Underwood and Jordan C. Brown have yet another reason to celebrate.

The former Bachelor star announced on Instagram Tuesday that he and Brown, a political strategist, are expecting their first child this fall. The pair are set to welcome a baby boy via a surrogate in October.

Underwood included a carousel of photos, including several sonogram images, with his announcement.

This entire journey has been a rollercoaster of emotions humbling, exciting, and truly eye-opening, he told HuffPost in an emailed statement. I couldnt be more thrilled to welcome our baby boy and really get to embrace Daddyhood in a whole new way.
