The Walking Dead’s Chandler Riggs celebrated the end of his high school career this weekend in epic fashion. It all began a few weeks ago when he took to Twitter to express his relief at finishing exams:

This weekend he finally graduated and posted about it on his Instagram:

If that wasn’t exciting enough, his TV dad and star of The Walking Dead Andrew Lincoln surprised him by showing up at his graduation after-party! His mother Gina broke the exciting news on her Instagram:

Look who surprised us at the party!

Not only that, but it appears other notable Walking Dead actors showed up for the festivities, including Danai Gurira and Lennie James:

Outside of The Walking Dead Chandler and Andy have always remained close. “I am definitely closest to Andy,” Riggs confirmed to Cryptic Rock when discussing who he related to more in the cast. For fans it’s exciting to see that Chandler’s relationship with the cast has transcended the show. Look forward to seeing all your (alive) favorites again when The Walking Dead returns for its eighth season this Fall.
