Los Angeles, California – There is baby bliss in the air for Olivia Munn and John Mulaney!

The actor and comedian are officially first-time parents!

On Saturday, People confirmed that that Munn (41) gave birth to a healthy baby boy on November 24, the day before Thanksgiving.

Both Munn and Mulaney were relatively successful at keeping the pregnancy under wraps and staying off the paparazzi's radar.

That is, until Mulaney made an appearance on Late Night with Seth Meyers in September, and dished on his and Munn's exciting news.

"I'm gonna be a dad!" Mulaney exclaimed, before adding, "We're both really, really happy."

While chatting it up with Meyers, the comedian also dished on his two nearly back-to-back rehab stints at the end of 2020 and the beginning of 2021, and how Munn somehow worked her way to his heart in the midst of it all.

At one point during the interview, Meyers offered up sound pieces of advice about fatherhood to Mulaney, and answered the 39-year-old's most pressing question: how to greet your newborn child.

"I don't want to be too formal, like, 'Hi, I'm John," Mulaney quipped, to which Meyers wittily replied, "They will not know your work, and so that is going to be a really tricky way to start it off."

In October, the rumor mill was running wild after celebrity gossip site Deux Moi caught wind that Mulaney and Munn might've split, though neither party ever acknowledged the alleged news.

Neither Munn nor Mulaney have commented on becoming first-time parents, or the current status of their relationship.

Given Mulaney is months away from hitting the road for his comedy tour, From Scratch, it's safe to assume he's written a bit about the whole experience and what he chose as his famous first words to his bundle of joy.
