The couple have been romantically linked since May, shortly after Mulaney split from his wife of six years.
Congratulations Olivia Munn and John Mulaney! On Tuesday, the 39-year-old comedian made an appearance on Late Night with Seth Meyers, where he revealed that he's expecting his first child with the 41-year-old actress.
During the episode, Mulaney candidly spoke about his challenging last year — which included a drug relapse, a stay in a rehab clinic, and a divorce from his wife of six years, Anna Marie Tendler.
"She held my hand through that hell, and we are having a baby, together", the Big Mouth star said of Munn with a big smile as host Seth Meyers congratulated him. "I'm gonna be a dad! I'm really -- we're both really, really happy."
Mulaney went on to credit Munn for helping him stay sober and healthy as he recovers from his cocaine and alcohol addiction. "Olivia and this baby have helped save me from myself", he said.
The couple have been romantically linked since May, shortly after it was reported that Mulaney had split from Tendler. Meanwhile, Munn was previously in a relationship with Tucker Robers.
Back in 2019, the actress opened up about her outlook on marriage and children during an interview with Entertainment Tonight.
"I have two dogs, two cats, so that's a lot just with the animals. I don't have kids. I mean honestly it's a lot. I can't imagine", she said at the time. "I've really come to a realization with myself that I'm already in my happily ever after. And if I want to have kids or want to get married then I'll do that, but it has to add to my life, you know? Everything has to add to my life."
