Actor Neil Patrick Harris has said that communication plays an important role in making his marriage work.

Earlier this month, Harris (How I Met Your Mother, Hedwig and the Angry Inch) and husband David Burtka celebrated their first anniversary

The men, together over 10 years, are raising 4-year-old twins Gideon Scott and Harper Grace.

“I think relationships just change by design,” Harris told Entertainment Tonight. “And so if you are too rigid about what your expectations are and then suddenly it changes, I think then you'd have more reason to want to look elsewhere for stuff.”

“But we have two kids and so that constantly changes, too.”

“At least in our relationship, communication is super important. Good friends of ours said that you need to talk it out. And if that means raising your voice, you need to raise your voice. And, like, know what you're talking about. Know where you're standing and then move past it, as opposed to letting stuff build up,” he added.

Harris returned to network television on Tuesday with the premiere of Best Time Ever, a variety show hosted and executive produced by Harris.
