Scott Wolf is including ex Kelley Wolf in a special family milestone.

Amid the former couple’s divorce proceedings, the Doc star shared a tribute to his and Kelley’s son Miller on his 13th birthday, including the Real World: New Orleans alum in a celebratory photo carousel on social media.

Among the snaps of the newly-minted teenager and his family, Scott, 57, included a pic of the mother-son duo sharing a tight embrace in a lush field while smiling for the camera. Alongside the images, the actor—who also shares kids Jackson, 16, and Lucy, 11, with Kelley, 49—penned a touching message to Miller, dubbing him “an American original.”

“A holder of light. A good time. A divining rod. Proof of life. Proof of love,” Scott wrote on Instagram Nov. 22. “A TEENAGER now. Fastening our chin straps for this one. Happy Birthday, MWW. You are love, you are loved.”
