Olivia Munn and John Mulaney are sharing the first photos of their newborn son.

Mulaney, 39, and Munn, 41, who welcomed their first child together last month, each took to Instagram Friday to post an adorable photo of the newborn, as well as reveal his name.

"Meet Malcolm Hiệp Mulaney," the comedian wrote alongside a photo of their baby boy sleeping while wrapped in a cozy blanket and a baby blue beanie. "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."

The first-time mom shared her own photo of Malcolm which showed the baby snuggled up against the same fuzzy blanket Mulaney shared in his post.

The "X-Men: Apocalypse" star kept the caption short and sweet, writing: "My Golden Ox baby. Malcolm Hiệp Mulaney. Happy holidays."

The couple didn't disclose any other details about their newborn son, such as when he was born. However, an unnamed insider told TMZ that Munn and Mulaney's child arrived on Nov. 24, the day before Thanksgiving.

The pair first sparked romance rumors in May, shortly after Mulaney split from his wife of six years Anna Marie Tendler.

In September, two months after he announced his divorce from his ex-wife, the former "Saturday Night Live" writer confirmed his relationship with Munn and her pregnancy during an appearance on "Late Night With Seth Meyers."

"In the spring, I went to Los Angeles, and met and started to date a wonderful woman named Olivia," Mulaney said. "I'm going to be a dad. We're both really, really happy."

During the interview, the comedian said Munn "held my hand through that hell," as he reflected on the past year, including his divorce from Tendler, a drug relapse and a stint in rehab. He also shared that the actress and their unborn child "helped save me from myself," while discussing his sobriety.

After some social media users questioned the timeline of Mulaney and Munn's relationship, the "Love Wedding Repeat" star told The Los Angeles Times that people are speculating "incorrectly" about them.

"They think they know our relationship so well. When in reality, they don't. There’s no way anyone could know what any of his relationships were or what our relationship is," she said.

In the same interview, Munn also admitted that she felt vulnerable as her due date approached and wanted to "just turn everything off."

"I'd rather close the door to that and just take care of myself and my baby," she added. "My brain hasn't been able to settle because it's just a constant feeling of you're doing it wrong. People tell me the baby will come and then you'll figure it out. But that doesn't stop the anxiety I feel right now."
