Olivia Munn & John Mulaney Expecting 1st Child!

New couple Olivia Munn and John Mulaney are expecting their first child just weeks after the comedian filed for divorce from wife Anna Marie Tendler.

During his Tuesday appearance on “Late Night with Seth Meyers,” the “John Mulaney & the Sack Lunch Bunch” star revealed the exciting news after Meyers pointed out that Mulaney has “had a year.”

“I went to rehab [for addiction issues] in September, I got out in October, I moved out of my home from my [ex-wife Tendler]. Then in the spring I went to Los Angeles and met and started to date a wonderful woman named Olivia [Munn].”

Though the funny man and the actress initially met at Meyers’ 2013 wedding, they became publicly romantic after Mulaney finished his 60-day rehab stint.

“I got into this relationship that’s been really beautiful with someone incredible, and we’re having a baby together,” Mulaney revealed.

While thanking Meyers for having him on the show, Mulaney added, “Olivia and this baby have helped save me from myself in this early journey out of recovery.”

On Wednesday, a source close to the couple told People that Mulaney and Munn, who will both be first-time parents, are “extremely excited.”

“They are both extremely excited about the baby,” the insider dished. “They couldn’t be happier.”

Back in May, People reported that the two entertainers were dating just days after it was announced that Mulaney and Tendler were ending their six-year marriage.

“This is very new, they’re taking it slowly,” a source close to Mulaney said at the time. “They met at church in Los Angeles.”

When Mulaney and Tendler’s split was announced, Tendler released a statement to numerous outlets, saying, “I am heartbroken that John has decided to end our marriage. I wish him support and success as he continues his recovery.”

At the time, Mulaney’s rep told Page Six, “John will not have any further comment as he continues to focus on his recovery and getting back to work.”

In late June, Munn and Mulaney were seen on a lunch date at Rick’s Drive In & Out in Los Angeles.

“They were having a great time during lunch, laughing and talking,” an insider told People at the time. “They were really enjoying each other’s company.”

The next month, Mulaney officially filed for divorce from Tendler at a New York courthouse.

Munn previously dated quarterback Aaron Rodgers for three years, from 2014 to March 2017.
