  • Mulaney said he and Munn started dating after he moved out of his home with his ex-wife

John Mulaney and Olivia Munn are expecting their first baby together.

The former "Saturday Night Live" writer appeared on "Late Night With Seth Meyers" Tuesday. During his appearance, the host told Mulaney, 39, "You've had a year," and this prompted the comedian to open up about what he went through in the past year.

"I packed a lot into this... Is it September now? I went to rehab in September, I got out in October, I moved out of my home from my ex-wife [Anna Marie Tendler]," he replied. "Then in the spring I went to Los Angeles and met and started to date a wonderful woman named Olivia."

He continued, "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!"

When Mulaney thanked Meyers for having him on the show, he once again mentioned his girlfriend and their unborn child. "Olivia and this baby have helped save me from myself in this early journey out of recovery," he said.

Mulaney confirmed Munn's pregnancy just days after she was spotted with a baby bump. The "X-Men: Apocalypse" star stepped out last Thursday in a pair of baggy tan sweatpants, a black crew-neck sweatshirt and red sandals. She was photographed walking through a parking garage sans Mulaney.

At the time, many were convinced that Munn was pregnant because she appeared to have a baby bump in the pictures.

"Olivia Munn is soooo pregnant," one user tweeted. "I can’t believe that Olivia Munn being pregnant with John Mulaney wasn’t just a crazy fan conspiracy," another wrote.

The rumors about Munn's pregnancy first surfaced in a viral TikTok video in June. In the short clip, the New York City comic duo @celebritymemoirbookclub said they were not in Mulaney's circle but were told about her pregnancy by someone who was.

On Friday, the duo reuploaded the video along with Munn's photos from Page Six where her baby bump was already visible.

A source close to the couple told People that Mulaney and Munn are "extremely excited" about their upcoming bundle of joy.

"They are both extremely excited about the baby," the unnamed source told the outlet. "They couldn't be happier."
