The Whirlwind Romance: From 2013 Meeting to 2021 Dating
The Mulaney-Munn connection is often framed as a rapid romance, but its foundation was laid years earlier. The couple first met in 2013 at a mutual friend’s wedding, where, as Munn later recalled, she was immediately smitten.
However, their romantic relationship did not begin until May 2021, shortly after Mulaney’s split from his then-wife, Anna Marie Tendler, became public. The timing drew significant media attention, as Mulaney was also fresh out of a 60-day stay in a recovery program for substance use.
The speed of their relationship was undeniable. By September 2021, just months after they began dating, Mulaney announced on Late Night with Seth Meyers that they were expecting their first child. This quick progression—from divorce and rehab to a new relationship and pregnancy—became a central narrative point in Mulaney’s subsequent stand-up material, including his Netflix special, Baby J.
The Arrival of Malcolm and Méi June: A Family of Four
One of the most significant and recent updates to their family life is the arrival of their second child, a daughter, in late 2024. The couple is now parents to two children, not just one, a detail that is often missed in older reports.
The Birth of Malcolm Hiệp Mulaney
Their first child, son Malcolm Hiệp Mulaney, was born on November 24, 2021. The couple introduced him to the world a month later, sharing heartwarming photos and establishing a new, lighter tone for Mulaney’s public persona. Malcolm’s middle name, Hiệp, is a nod to Munn’s Vietnamese heritage.
The Surprise Arrival of Méi June Mulaney
In a surprise announcement, it was revealed that John and Olivia welcomed their second child, a daughter named Méi June, on September 14, 2024, via a gestational surrogate. Munn publicly shared the news a few days later. This choice of surrogacy, while private, reflects the couple’s desire to expand their family despite the health challenges Munn was facing, including her ongoing breast cancer treatment and a medically necessary hysterectomy.
Olivia Munn’s Courageous Health Battle and Mulaney’s Support
A major focus of their recent life together has been Olivia Munn’s battle with breast cancer. Diagnosed in 2023, Munn has been remarkably open about her journey, which included a double mastectomy and five surgeries.
During the 2025 TIME Women Of The Year Gala, where Munn was an honoree, she spoke about giving herself grace and the continuous nature of her treatment. John Mulaney has been a pillar of support throughout this process, often accompanying her to appointments and public events. The depth of their commitment was cemented by their wedding in July 2024, which occurred amid these profound personal challenges.
The 2024 Marriage and The 'Unglmaorous' Proposal
Despite the public scrutiny and life-altering events, the couple officially tied the knot over the Fourth of July weekend in 2024. While they kept the news quiet initially, recent details about their engagement and wedding have surfaced, offering a humorous and intimate look into their private life.
In a 2025 revelation, Olivia Munn shared the unglamorous and hilarious details of Mulaney’s proposal. She recounted an elaborate lie she told to avoid spoiling the surprise after a friend accidentally let slip that Mulaney was planning to pop the question. The actual moment, according to Munn, involved Mulaney proposing on a balcony with a funny backdrop—a sign that read "No Diarrhea." This anecdote perfectly captures the blend of high-profile romance and down-to-earth humor that defines their relationship.
