John Mulaney and Olivia Munn gave the world its first look at their newborn son, Malcolm Hiệp Mulaney.

“My Golden Ox baby. Malcolm Hiệp Mulaney,” Munn wrote over the weekend, alongside a photo of her baby who is adorned with a blue cap and surrounded by a white blanket. “Happy Holidays.”

Mulaney shared a similar photo, alongside a caption that read, “Meet Malcolm Hiệp Mulaney. He has his whole life ahead of him. He hasn’t even tried seltzer yet. I’m very in love with him and his whole deal. Happy Holidays.”

TMZ previously cited “sources with direct knowledge” that Munn “secretly” gave birth on Nov. 24. Mulaney and Munn were  first reported to be dating back in May, when an insider told People that they met at a church after it was revealed Mulaney and Anna Marie Tendler, his wife of six years, were separating.

“In the spring, I went to Los Angeles and met and started to date a wonderful woman named Olivia. … I met her, actually, for the first time in life at your wedding,” Mulaney told Late Night host Seth Meyers during an interview in September when he announced the baby was on the way. 

Also in the discussion, Mulaney added that meeting Munn was a “very lucky thing.” 

Mulaney is coming off a very public stint in rehab, which he also discussed with Meyers. 

“I went to rehab in September, okay?” Mulaney said at the time. “I got out in October, I move out of my home from my ex-wife, I host Saturday Night Live on Halloween, I relapse on drugs after the show. Not directly after, I just mean, you know, after.”

Congrats to the happy couple.
