In what felt like a quickfire combination of divorces and separations, rumors, and late-night confessions, Olivia Munn and John Mulaney went from a Deuxmoi-fueled fantasy to a real-life couple. Though the two have known each other for nearly a decade, it wasn't until 2021 that the pair settled down, squashed all the speculation, and welcomed a child together. Here's what you need to know about the two, from how talk show host Seth Meyers connected them to their darling little boy, Malcolm.

September 2013

During an appearance on Late Night With Seth Meyers, Mulaney shared that he met Munn for the first time at Meyers's wedding to Alexi Ashe.

In 2015, Munn shared her side of the story, telling HuffPost Live that she was "obsessed with hanging out with and talking to" Mulaney that night. "We were at a wedding together and I was like, 'Oh my gosh, do you and your fiancé want to go have dinner or something and go hang out?'" she said.

After reports that Mulaney checked into rehab, Munn offered her support on Twitter with a sweet message accompanied by heart and lightning bolt emoji.

Mulaney and his wife, Anna Marie Tendler, announce that they're separating after six years of marriage.

"I am heartbroken that John has decided to end our marriage," Tendler said in a statement to Page Six. "I wish him support and success as he continues his recovery."

The couple officially divorced in July.

People published the first photos of Munn and Mulaney together. They're seen together at Rick's Drive In & Out in Los Angeles. Mulaney told Meyers that he moved to L.A. in the spring of 2021.

Fans spot Munn at Mulaney's comedy shows, too.

"Olivia and John are going strong," a source told Us Weekly. "She has been sneaking into some of his shows and loves them ... Olivia is so smitten."

The biggest news during Mulaney's appearance with Meyers was that he and Munn were expecting.

"I'm gonna be a dad ... we're both really, really happy," he said. "You guys saved me from drugs, and Olivia and this baby have helped save me from myself in this early journey out of recovery. And yeah, I don't have a joke for that. I'm really grateful to you."

Munn told Access that was feeling great after the news broke.

"Just the outpouring of love and support has been really amazing," she said. "There has been a really big mom tribe that comes up. I've heard about it, but they really come up in full force. There's a really great dad tribe, too, everyone comes up is really supportive and it means so much to me."

October 2021

Rumors of a breakup start to swirl online, though neither Munn nor Mulaney comment. A source told Us Weekly that the relationship is "imperfect" but they see each other as works in progress.

"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," the source said. "Olivia and John still have to decide what kind of future they're going to have together, if any. It's a time of uncertainty, for both of them."

"Becoming a mom was always more important to her than settling down in a conventional way," a second source added. "She's a real feminist and doesn't need a man by her side 24/7. She never has."

November 24, 2021

Munn and Mulaney welcome their first child together, a son named Malcolm Hiệp Mulaney. The two would keep the news to themselves until the holidays.

"Meet Malcolm Hiệp Mulaney. He has his whole life ahead of him. He hasn't even tried seltzer yet," Mulaney shared in an Instagram post on December 24. "I'm very in love with him and his whole deal. Happy Holidays."
