"The Walking Dead" star and actress Burton, who share two kids, officially became husband and wife on Saturday, October 05.
The media just assumed the couple was married, but Hilarie revealed the truth in an Instagram post over the weekend.
"This past weekend was the best of my entire life," she wrote. "There are dozens of thank yous I need to make. So bear with me over the next week as I gush over the amazing group of people who gave us this beautiful moment. But before we do any of that, Jeff and I just want to put it out there that WE GOT MARRIED! For real."
"We've lived as husband and wife for a decade. We've built a family, and a farm and found our community. For years, publications have reported that we got married in 2014 or 2015 and that I've been married and divorced before. All untrue. But WE knew our truth."
"So it felt silly to try and correct anything. Here's the God's honest fact: From the moment I met @jeffreydeanmorgan, he was my husband. Rather than make vows right out of the gate, we lived them. For over ten years. The good times and the bad. Standing up there with our children at our sides - celebrating all that has been - was bliss. I love you Jeffrey. I love our intimate group of friends and family who joined us. I love the various circles of loved ones who have supported us over the years. It was private and magical and everything I dreamed. So yeah. I'm Mrs. Morgan. 10.5.19."
