Dermot Mulroney is back on our TV screens as Chicago Fire’s new chief, Dom Pascal – and we are loving watching him in the new 13th season.

The 60-year-old is a big name in the acting world and is perhaps best known for starring opposite Julia Roberts in the 1997 romcom, My Best Friend’s Wedding. Since then, he’s appeared in a wide range of blockbuster films and major TV shows, including Zodiac, Anyone But You, and New Girl. But how much do you know about his life away from the cameras? Find out about his family life here, including his famous wife, Prima Apollinaare, and his Oscar-winning ex.

Dermot’s musician wife Prima Apollinaare

Since 2008, Dermot has been happily married to Italian musician, Prima Apollinaare, formerly known as Tharita Cutulle. The professional cellist and singer-songwriter reportedly changed her name in 2015, although hasn’t publicly explained why.

Prima is incredibly supportive of Dermot’s career and has watched nearly all of his movies. She told Entertainment Weekly earlier this year: “I watch all of his movies. To be honest with you, I think the only movie I did not see of his is Scream VI, not because I don’t care for it, it’s just I don’t care for the genre. But I always think his movies are excellent. I really like it.”

Posie’s litter-mate and life partner,” he continued. “Weight reduction plan, down 2.5 lbs! tough for a #chubbychihuahua hoping for single digits soon.”

Dermot’s famous ex-wife

Long before his relationship with Prima, Dermot was married to Hollywood actress Catherine Keener. The 65-year-old is known for her roles in Being John Malkovich and Capote, both of which earned her Oscar nominations. She also starred in The 40-Year-Old Virgin, Into the Wild, Percy Jackson & the Olympians: The Lightning Thief and Get Out.

Dermot and Catherine tied the knot in 1990 before going their separate ways 15 years later and eventually signing divorce papers in 2009.

During their marriage, the pair welcomed a son named Clyde, who was born in 1999.

Dermot’s approach to parenthood

Back in 2016, Dermot described himself as a “pretty easy-going guy” when comparing himself to his “buttoned up” Dirty Grandpa character David Kelly.

“I’ve lived in California now for thirty years and travelled around. I’m a pretty easy-going guy, so yes, not so straight and narrow as a parent,” he told The Hollywood News.

Dermot also said he’s not too keen for his kids to follow his footsteps in pursuing an acting career. “I try to keep arts in front of them, whether it’s music or even just museum trips,” he said. “I don’t expect anything of them – it’s hard enough for everyone just to get their homework done at night. Let’s just get them through grade school, and then see. We’ve all certainly seen that being a child actor is unhealthy so, I wouldn’t do that.”
