Guess it’s gonna stick. Despite widespread assumptions, Hilarie Burton and Jeffrey Dean Morgan weren’t officially married until Saturday, October 5th.

Burton shared the happy news on Instagram: “This past weekend was the best of my entire life. 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.”

The One Tree Hill alum and her Walking Dead beau were first introduced in 2009 by Morgan’s Supernatural costar Jensen Ackles, who married Burton’s castmate and friend Danneel Harris.

Despite the confusion over their marital status, Burton said the perception felt true to them: “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.”

The 37-year-old concluded: “It was private and magical and everything I dreamed. So yeah. I’m Mrs. Morgan. 10.5.19.”

The 53-year-old Morgan piped up: “I’d say words… but there aren’t any. Mrs Morgan…. I love you. Thank you for making me the luckiest man in the world. Xojd.”

The pair share son Gus, 9, and daughter George, 19 months.
