I got into this relationship that’s been really beautiful with someone incredible. And we’re having a baby together. I was nervous when I was about to say the news! Olivia and this baby have helped save me from myself in this early journey out of recovery.”

I’d be with him on the road, and I would hear him tell this joke, and I did feel a sense of healing with it.”

While hosting an episode of SNL, the comedian talked about addiction, rehab, the intervention that saved him, and his new life. “‘Life is a lot better and happier now,” he said. “I have a 12-week-old son. He is a pretty cool guy for someone who can’t vote. His legs are like little calzones, and I want to eat him.”
He recalled, “We were in the delivery room. My girlfriend had just given birth to him, and he’s crying a little, so they bring him over to this warmer on the other side of the delivery room, and they put them on the warmer under this big bright light, and light is just shining in his eyes. He just looked up at the light, and he was annoyed. But he didn’t say anything. I was like, ‘That’s my son.’ A polite man in an uncomfortable situation, but he’s not going to make a fuss.”

In an interview with Vogue on May 12, 2024, Mulaney shared his experience: “‘Olivia and I have been through a lot of things together in the past couple years, just side-by-side, supporting each other through anything. And as her guy, I felt both scared and protective. Even with Malcolm in her lap and me there holding her hand, she was going to be physically fighting this disease alone.’”

On September 22, the couple announced they had welcomed their second child. Méi June Mulaney was born on September 14.
“Méi June Mulaney came into the world September 14, 2024, the year of the dragon🐉,” Munn captioned a post of her and Mulaney holding Méi in the hospital room. “I had so many profound emotions about not being able to carry my daughter. When I first met our gestational surrogate we spoke mother to mother. She showed me so much grace and understanding, I knew I had found a real-life angel. Words cannot express my gratitude that she kept our baby safe for 9 months and made our dreams come true.”
She added, “I am so proud of my little plum, my little dragon for making the journey to be with us. My heart has exploded. Méi (pronounced may) means plum in Chinese 梅💜.”
Mulaney shared a post with the same photo, writing, “Méi June Mulaney came into the world September 14, 2024, the year of the dragon🐉. We stole so much stuff from the hospital. I love my little girl so much.”
October 2024
On October 5, Munn was on a panel during Hello Sunshine’s Shine Away event in Los Angeles, where she discussed the IVF process and her own decision to freeze her eggs knowing she wanted another child with Mulaney, specifically a girl. She froze her eggs again during her cancer battle when she was 42-years-old.
“I told John, ‘I won’t feel good until we get two more [embryos that are girls] so I need you to just be on my side and let me go through this. And I know I’m putting myself at risk, but I just have to do this,’” Munn explained. “And he said, ‘I’ll support whatever you want to do.’ We got home that day and the doctor said, ‘I got the results back, and it’s the dream. You have two healthy baby girl embryos.’ And now we have Méi.”
December 2024
On Wednesday, December 25, Munn shared pictures from Christmas with Mulaney and the kids. In one picture, she kissed Méi June on the cheek in front of their gorgeous Christmas tree, in another it was Mulaney kissing the infant.

“The house is a mess, Malcolm got safety glasses personally from the penguins of Madagascar and Méi is 100 days old today. All my Christmas wishes came true,” she wrote in the caption.
In her Stories, she also shared pictures of a late night and an early morning with the kids.

June 2025
In an interview with People, Munn admitted she “felt like an expectant father” as she and Mulaney awaited their daughter’s arrival via surrogate.
“A lot of times people say, ‘Oh, the dads don’t really connect with the baby until it’s right there in front of them,’” she explained. “The dads, they’re not carrying the baby. I carried Malcolm, so I understood from the very genesis, like, okay, I’ve got a life in me. Your body is changing and your energy is changing and your hair is changing and everything’s changing, so it feels very real all the time.”
Ahead of Méi’s birth, Munn said, “[It] was the first time I was like, ‘Oh wait, is this what it’s like to be an expectant dad?’ It was a little bit of, ‘Oh wait, she’s coming.’ I felt like an expectant father.”
But her surrogate helped to make Méi’s arrival “very real,” speaking with Munn “all the time” and sending videos.
