John Mulaney and Olivia Munn are going to be parents. Mulaney announced that the actress was pregnant during his appearance on Late Night with Seth Meyers on Tuesday.

"You've had a year," Meyers said to the comedian, to which Mulaney replied, "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 continued, "Then in the spring I went to Los Angeles and met and started to date a wonderful woman named Olivia."

He then went on to share the big news, "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."

The comedian also added that "Olivia and this baby have helped save me from myself in this early journey out of recovery."

A source also exclusively told People that the couple is very "excited" about their addition on the way. "They are both extremely excited about the baby," the source shared. "They couldn't be happier."

The Love Wedding Repeat actress and Mulaney were first reported to be dating back in May, but have actually been friends for years. Mulaney and Tendler were married for six years before they announced their separation in May.
