“The Walking Dead” actor Norman Reedus and his former partner, Danish model Helena Christensen, reunited to celebrate their son’s high school graduation this week.

Christensen, 49, posted a photo on Instagram Tuesday of her with Reedus and their 18-year-old son, Mingus Lucien Reedus.

“We’re so proud of you,” she wrote in the caption, adding the hashtag #Classof2018.

She later posted a clip of the group walking together, with Mingus in the middle donning his gown.

The proud mom then posted four more photos from the event.

“Proud as hell! 👨‍🎓❤️”” she captioned the Instagram gallery.

E! reports that Christensen posted a video of Reedus hugging his son, too.
