Steven Yeun, best known as beloved Glenn Rhee on AMC’s The Walking Dead, married his longtime girlfriend, photographer Joana Pak in an intimate ceremony on Saturday at Los Angeles’ Paramour Estate.

Several of Yeun’s former costars were there to watch him tie the knot, including Andrew Lincoln and Sarah Wayne Callies.

Callies took to Instagram to share a photo of herself with Lincoln’s wife Gael Anderson just before the ceremony.

“Wedding ready….” she captioned the black-and-white photo.

And while Yeun posted a photo of his wife lounging on a chaise chair on their big day, many of the couple’s family members provided sweet tributes to their beloved newlyweds.

Pak’s sister-in-law Kayce also shared an adorable photo of the bride and groom.

She captioned the post, “Getting to celebrate the love between these two, last night, along with all their friends and family was so beautiful and special!! This whole week has been an awesome, family-filled, fun time and it’s been so great! (We’ve also gained a brother in-law from it!) #loveyouguys #pakpack.”
