    “After 27 years of marriage, it is with great sadness that we have come to the difficult decision to file for divorce,” the couple said in a statement posted on their show’s website Friday. “We are proud of what we have accomplished together, including raising four wonderful children who have grown to become remarkable adults and building our strong and ongoing successful businesses,” they said.

    Twins Jeremy and Zack, 25, daughter Molly, 21, and son Jacob, 18, co-star with their parents on their show. They said that their children and growing family remain their priority.

    Matt and Amy filed for divorce in Oregon on Friday.
