Olivia Munn and John Mulaney are expecting a baby.
The stand-up comedian confirmed the pregnancy news Tuesday on “Late Night with Seth Meyers” while discussing their whirlwind relationship.
“I went to rehab in September . I got out in October. I moved out of my home from my ex-wife [Anna Marie Tendler]. Then, in the spring, I went to Los Angeles and met and started to date a wonderful woman named Olivia,” Mulaney, 39, began.
“And we’re having a baby together,” he continued. “I was nervous when I was about to say the news!”
A source exclusively told Page Six the couple are delighted by the news, which comes less than four months after their romance was first revealed.
The baby will be the first child for both stars.
“Newsroom” alum Munn, 41, was spotted Thursday in Los Angeles, wearing baggy sweats and a sweatshirt as she walked through a parking structure.
And in June, she was spotted in a similar outfit as she left Mulaney’s LA home.
Their relationship is said to be going strong after Page Six revealed in May that the “Kid Gorgeous” star was divorcing his wife of six years, Tendler, following his 60-day stay in rehab for substance abuse.
“I am heartbroken that John has decided to end our marriage,” the artist, 36, told us in a statement at the time. “I wish him support and success as he continues his recovery.”
Mulaney has been open about his battles with addiction, and while making his comeback at a string of gigs at NYC’s “City Winery” in May, he recalled how his celebrity pals — including Bill Hader, Natasha Lyonne, Seth Meyers, Fred Armisen and his comedy partner Nick Kroll — had organized an intervention and begged him to go to rehab.
He has continued to work on his sobriety since leaving rehab.
Following his first comeback gig, Rolling Stone critic David Fear tweeted, “So John Mulaney at City Winery was … intense…90 mins that was mostly processing his intervention and rehab experience.”
Fear also shared a joke from the set in which Mulaney said, “When I’m alone, I realize I’m with the person who tried to kill me.”
Munn has been romantically linked to Aaron Rodgers, Chris Pine, Justin Timberlake, Matthew Morrison and Joel Kinnaman in the past.
