The "Walking Dead" star and his ex posted several family photos to document their son Mingus' big night. "We’re so proud of you ❤," Christensen wrote, sharing a photo of the trio with the 18-year-old in the center wearing his cap and gown.
Reedus looked like a proud papa as he took the time to praise his ex-girlfriend. "Props to this lovely lady ??❤ (he graduated!!)," the actor wrote, posting a pic with Christensen. It's worth noting, the two were dressed to the nines for a high school graduation — Reedus wore a suit and black tie while Christensen shined in a green, floral gown.
The "Walking Dead" star and the Danish model dated for several years and have remained friends for the sake of their son. Reedus' current girlfriend, Diane Kruger, is rumored to be pregnant and was not present at the graduation.
