As evidenced in photos shared on social media, the two stars weren't the only proud family members present to celebrate the special occasion. Their 14-year-old son, Sasha, was also on hand, as were their new significant others. While Schreiber has been dating Taylor Neisen, Watts is currently in a relationship with her former Gypsy co-star, Billy Crudup.
The two couples documented the day by smiling for a group photo with the 13-year-old graduate.
As Watts aptly captioned the shot on Instagram, "Congratulations to Kai ⚡️🎉Class of 2022 #modernfamily ❤️ #graduation."
Most recently, Reese Witherspoon and Ryan Phillippe were both on hand as their son, Deacon, had his own unique version of a high school graduation ceremony in a backyard. "Homeschool graduation feat. @matt_sinn & @benmassing," Phillippe quipped in part of an Instagram post. "(i played principal)."
