In fact, a second source told the outlet that not only are they very much together as they prepare to welcome their first child, but that things have become "very serious." The insider added the Ride Along 2 star is "very excited to be a mom," and "grateful it happened."
"In the spring, I went to Los Angeles, and met and started to date a wonderful woman named Olivia — Olivia Munn," Mulaney — who split from wife Anna Marie Tendler in May — said. "It is a very lucky thing to have met this woman."
The Chicago native also told Meyers about how Munn helped him to navigate his subsequent divorce and rehab stay for substance abuse. "She's kind of held my hand through that hell, and we are having a baby together," he continued to gush about his pregnant girlfriend.

As OK! previously reported, friends of the couple had previously expressed their relationship may not be as stable as it appears to be. A source spilled the duo's romance was “an imperfect relationship from the start.”
“Even though Olivia’s going to be a wonderful mother and has great support behind her, Olivia’s friends just don’t see these two being a couple in a year’s time," an insider close to the Hollywood star claimed.
While both Munn and Mulaney cannot wait to meet their child, the two "still have to decide what kind of future they’re going to have together, if any,” the insider alleged.
