The American actor Jeffrey Dean Morgan, known for his role as the villain Negan in the horror series The Walking Dead , was secretly married on Saturday to One Tree Hill actress Hilarie Burton.

It is the second marriage for Morgan. The 53-year-old actor and his 37-year-old bride announced the news by posting a black-and-white photo on Instagram.

“I want to let you know that we are married,” Burton wrote with the photo.

The two had been in a relationship for ten years. Burton on that: “We have been living as men and women for ten years. It was previously written that we would already be married in 2014 or 2015 and that I have already been married and then divorced, but that is not true. But we knew the truth and it felt strange to try and correct that. “
