Matt Bomer Shares the Secrets Behind His Long-Lasting Marriage (Exclusive)

Matt Bomer’s key to a successful marriage was actually someone else’s key first.

“My grandparents were together from the time they were teenagers on, and I used to ask them and they’d tell me, ‘One day at a time,’” the actor tells ET. “So, I guess I try to adapt that philosophy, but also just having perspective. You know, at the end of the day, the family and our home life is the most important thing and keeps everything else in perspective.”

The 40-year-old quietly wed his longtime love, power publicist Simon Halls, back in 2011. The couple share three sons, Henry, Walker and Kit, though Bomer admits they’re not very familiar with his work.

“I just have to make sure that I start working on more things that they can see!” the American Horror Story vet notes. “’Cause they’re like, ‘You do this, but then we can’t watch it.’ I’m like, ‘When you’re older maybe!’”

That includes Bomer’s latest project, stepping behind the camera on FX’s The Assassination of Gianni Versace: American Crime Story. He made his directorial debut on episode eight, “Creator/Destroyer.” ET caught up with him at a For Your Consideration event for the series at the Directors Guild of America in Los Angeles, ahead of its finale, airing Wednesday on FX.

“It’s a big responsibility,” Bomer says of directing the series. “It’s a big stage to step on to, to make your directorial debut, so I took it very seriously. I spent about four and a half months working on the project, from research I did, to here at the DGA, I did an intensive. I shadowed two of the great directors we had, Dan Minahan, Gwyneth Horder-Payton, and just exhaustively, I think I read over 300 pages of books on directing, and reached out to friends who were kind enough to mentor me … so, I guess it meant a lot of hard work.”

The actor lit up when asked what a nomination or award for his directing work would mean, saying, “I don’t think there are words for it, really.”

Next up for Bomer is another Ryan Murphy project, the Broadway revival of The Boys in the Band. The play officially opens on May 31 at the Booth Theatre in New York City.

“It’s the 50th anniversary of the play, The Boys in the Band,” Bomer notes. “It’s really the first mainstream gay play that there was, and I think it’s incredible how far we’ve come in 50 years, but also important to look back on what life was like for people 50 years ago in the LGBT community, people who couldn’t go out and dance together in public without being arrested, who had to live in the shadows. And so, this play is really about a group of friends who are having that experience together and how it affects their relationships in their lives, and what there hopes and dreams are.”

“It’s gonna be fun!” he adds. “Come celebrate the birthday party with us and I hope you have a good time.”

Max Greenfield Says He’s Just ‘Gonna Be a Dad for a While’ After Final Season of ‘New Girl’ (Exclusive)

Max Greenfield is preparing for life after New Girl.

“I’m gonna be a dad for a while,” he shares of his post-show plans. “That’s my favorite job.”

The actor has two kids, daughter Lilly and son Ozzie, with his wife of 10 years, Tess Sanchez. He tells ET that his parenting skills came in handy while working on the final season of New Girl, premiering Tuesday, April 10, on Fox.

“We do a flash forward,” he teases. “It’s like a three-year flash forward, so it’s fun. You get to see the characters that you’ve sort of known for the past six seasons in a little bit of a different light. Specifically, you know, Schmidt and Cece, who are now parents.”

It was revealed in the season six finale that Greenfield’s character, Schmidt, and his wife, Cece (Hannah Simone), were expecting their first child.

“It wasn’t like much of a stretch,” he says of playing Schmidt as a dad. “I was like, ‘Ugh! I was trying to get away from this. Now I have to come do it at work, too?’ It made me realize, ‘cause you know, you like, relate to being a parent and you want to play out those scenarios on set, or in some sort of acting role, and then you get there and you do it and you’re like, ‘No! No! This is not what I want to be doing.’”

Still, Greenfield notes the parenting storyline was something fresh for the series.

“It was sort of bittersweet, you know?” he says of wrapping production on the show. “I mean, it’s been seven years. I don’t think there were many more stories to tell. But, to say goodbye to a show and the people that you worked with for a really long time is difficult and then you’re, like, tasked with finding something new and going, oh man!”

Greenfield definitely found something new on The Assassination of Gianni Versace: American Crime Story, playing Ronnie, an acquaintance of spree killer Andrew Cunanan. ET caught up with the 37-year-old at a For Your Consideration event for the series ahead of its finale, airing Wednesday on FX.

“It was very meaningful to be a part of this show,” he shares. “I think it’s a really strong message, I always love working with Ryan [Murphy]. He has such a specific point of view and, and you know, I had sort of only known what the first two episodes were going to look like and didn’t know anything beyond that. As I’ve watched the show, you’re like, this is just… this is a really stunning piece.”
