Co-parenting are tame for Reese Witherspoon and Ryan Phillippe.
The couple of years met to give their 18-year-old son, Deacon, a homeschool graduation, where they posed for family photos.
Thursday, the high school graduate appeared in a slideshow on Instagram wearing an orange cap and robe.
Witherspoon, 46, wore a polka dot dress, while her previous Cruel Intentions co-star, 47, wore a black cap and gown of his own.
Phillippe captioned the post to explain his appearance as the i played principal.
The star of I Know What You Did Last Summer shared a video while he and his friends shaking Deacons hand before the grad turned his caps tassel, marched around a swimming pool and threw his hat into it.
Witherspoon pulling down to remove the cap from the water, the footage came to an end.
Phillippe wrote that Reese took the cap grab.
In the social media, Deacon described his father as the best dad, while Justin Long wrote, and all three of you might be high school graduates! #VampireFamilyVibes #Fampire.
From 1999 through 2007, the proud parents adopted their oldest daughter Ava, 22. (After their separation, Witherspoon and Phillippe have arranged to reunite their son Tennessee, 9, and daughter Kai, 10, together with husband Jim Toth and ex Alexis Knapp.)
Over the years, the executives have met multiple times, most recently sharing photos from the Deacons birthday celebration.
Happy 18th birthday to Phillippe, our adorable, intelligent, talented and caring son, who captioned a black-and-white Instagram photo last October. You are a true light in this world and are so honored by everyone who knows you.
In May, the Shooter alum sent his son to prom, but Witherspoon did not appear in the Instagram Story pictures he posted before of the school dance.
Instead, the Big Little Lies star uploaded her own event pic, writing, and love this guy.
