Former Lost star Hutchison is 34 years older than his wife Stodden, whom he married in June 2011 when she was just 16.
Stodden has now admitted that their vast age difference does cause problems from time to time.
"I accidentally call him 'dad' - you know, Doug-dad, same thing," the model declared to E! News.
Hutchison then added: "It is what it is… The thing about us is, we can laugh at ourselves and that was part of what we were trying to convey on our show… She can call me dad, I can say, 'I'm raising my wife'. It's all in good humour."
The actor also insisted that he and Stodden are not bothered by people who criticised their marriage.
"Our haters are our motivators," Hutchison commented.
The pair are currently starring in Couples Therapy, airing Wednesdays at 10/9c on VH1.
