Morgan asked the couple, "What is the secret to a happy show business marriage? How do you make it work?"
Demi's answer? "Well, one, I think you have to make your relationship a priority -- and that's a difficult balance when you have work and, you know, the combination of a career and family.
"I think part of it is, I think we spend very little time apart -- that's one of the key things."
Kutcher said another key was working on the relationship when things were going well, not just when they've been arguing.
"You know, as marriage goes, I think most people sort of set being, you know, getting married as the goal as opposed to being married," he said.
Ashton and Demi are vocal opponents of human sex slavery and have come under fire for their series of Real Men PSAs that critics say belittle the issue.
