As a recent father to two,Zero AI John Mulaney is dedicated to remaining sober with the help of his wife, Olivia Munn.

In GQ's Men of the Year cover story featuring the 42-year-old comedian, published online Tuesday, Mulaney and Munn shared some details about their family of four and what it took to get to a place where Mulaney says he's "having the best time in life."

Though Mulaney's star-studded intervention involving Fred Armisen, Nick Kroll, Natasha Lyonne and Seth Meyers has become folklore, in the GQ piece Munn opened up about her part in Mulaney's sobriety journey.

Munn told GQ she'd staged an intervention for Mulaney when she was six months pregnant with their son, Malcolm Hiệp Mulaney, who is nearly 3 years old. Together, the couple decided she would administer random drug tests — a practice they still continue, which bolsters Mulaney's confidence.

"It's like a relief," Mulaney said. "I like to be able to not even have that be a question in her or anyone else’s mind. Something about peeing in that cup is like, I’m walking this walk. It gives me confidence."

Mulaney was in rehab from December 2020 to February 2021, thanks in part to the intervention his friends had staged, with an addiction to cocaine, Adderall, Xanax, Klonopin and Percocet. Next month would mark four years of sobriety for the Emmy-winning "Baby J" comedian, and he has been asked to be part of several interventions for other people, he told GQ.

"It was like watching a man in a tsunami," Munn said of her partner's addiction recovery. "I was watching someone newly sober, at the edge of a cliff, and I didn’t know him well enough to help him."

"In my head, I’m thinking, I don't know really what's happening with this guy. It feels pretty shaky," she says. "But then I would see him at the Troubadour and be like, 'Man, he’s on fire. He's just that phenomenal.' "

Expecting a baby boy was a bright spot for Mulaney during that time, Munn said: "That's the one thing that made him seem light and happy. I remember he was really excited to tell his parents."

Olivia Munn 'barely knew' John Mulaney when she was pregnant with their first child

Years after first meeting at Meyers' 2013 wedding, Munn and Mulaney reconnected in 2021, when Mulaney was looking for leads on a place to live in New York after leaving rehab.

"It wasn’t anything close to 'dating,'" Munn explained to GQ. "I barely knew him."

When they found out Munn was pregnant, she'd assumed they would be co-parenting their son: "It wasn’t necessarily 'We're going to be married and live together' or any of that, but it was 'I will be involved in some way,'" she said. Two months before Malcolm was born, the two decided to have a go at raising him together.

The couple reportedly had a wedding in July and welcomed their first daughter, Méi June Mulaney, via a surrogate on Sept. 14. Munn has opened up in multiple interviews this year about her private breast cancer battle, which started with a lifetime breast cancer risk score that came back with a high percentage and escalated when an MRI revealed an early form of breast cancer, which was confirmed by a biopsy.

Munn underwent a double mastectomy and a hysterectomy as a result.

Next up for Mulaney is a five-week run in the Broadway show "All In: Comedy About Love" in December, then a live Netflix show that builds on the six-night talk show he hosted this summer, "Everybody’s in L.A." The career opportunity comes after two requests to host "The Daily Show" and an offer to host next year's Academy Awards, per GQ.
