NEED TO KNOW
Ted Danson and Mary Steenburgen have been married for 30 years
Shortly after they celebrated the milestone anniversary in October, and ahead of Steenburgen joining season 2 of A Man on the Inside, they spoke to PEOPLE about their life together
Steenburgen gushes that Danson "really knows who I am," but with that kind of honesty comes conflict sometimes — but only about one thing
There's only one thing that makes a fight break out betweenTed DansonandMary Steenburgen.
The couple, whocelebrated their 30th wedding anniversaryin October, are a perfect fit for each other, as Steenburgen tells PEOPLE that she has "never been...as known as I am by him."
"He really knows who I am. He knows the most petty, small, ugly parts of me. And he knows the highest, soulful, aspirational parts of me and somehow loves the whole thing," she says. "And I've been extremely honest with him in this relationship, and that was important to me — and we both feel that."
Danson, 77, is in agreement, but he admits that he's the one who stirs up trouble. "The only time we fight or get angry with each other is when I am wrong," he tells PEOPLE.
"She'll point something out to me that disappointed or angered or hurt her feelings or something, and I just refuse to be that person," he explains. "'No, I'm not that person that you just described,' and so I argue and resist until I finally go, 'Yeah, yeah. That's me.' "

While that's a point of struggle for her husband, Steenburgen, 72, says, "I actually know and cop to how deeply imperfect I am. Ted doesn't like doing that."
"Yeah, I don't like doing that myself," Danson admits.
The couple, who started dating after they starred inPontiac Moontogether, reunited onscreen inA Man on the Insideseason 2, which Steenburgen said she felt "so honored and lucky" to be part of.
"I listened to Ted come home throughThe Good Placeand then the first season of this show just delighting in the extraordinary scripts and a cast and crew that he's so proud to work with," she said. "And I was always a little envious. So to be asked to be a part of this was so thrilling."

Danson echoed his wife's sentiments,calling her casting a "dream come true."
"We both love being actors; we both love the process," he said. "So we spent two and a half months together getting up, going to work early, but just giggling the whole time because of what we got to say and do. It was just really a great opportunity."Never miss a story — sign up forPEOPLE's free daily newsletterto stay up-to-date on the best of what PEOPLE has to offer, from celebrity news to compelling human interest stories.
