Their relationship began with a reconnection and evolved through unexpected turns. Today, Olivia Munn is known not just as an actress but as John Mulaney's wife, and their story is filled with quiet strength, resilience, and deeply personal moments.

John Mulaney's wife, Olivia Munn, first entered his life under unexpected circumstances. The two initially met briefly in 2013 at Seth Meyers' wedding, during a time when Mulaney was still married to his ex-wife, Anna Marie Tendler. Years later, their paths would cross again — this time under very different conditions.

In early 2021, following his stay in rehab, Mulaney was looking for a new place to live in New York. Munn, who had kept in touch, connected him with a friend who could help. What started as a simple exchange of thanks soon developed into something more. Here is everything we know about John Mulaney's wife, Olivia Munn.

Inside John Mulaney and Olivia Munn's Intimate New York Wedding

In July 2024, John Mulaney and Olivia Munn quietly made their relationship official. The couple, who share two kids, tied the knot in a small, intimate ceremony held at a friend's home in New York state.

According to a source close to Mulaney, the wedding was attended only by their son and a witness, keeping the occasion private and personal. The ceremony was officiated by "The Newsroom" actor Sam Waterston, Munn's co-star, as confirmed by People.

John Mulaney's Wife Olivia Munn Faced Breast Cancer Battle Before Their Wedding

Just four months before marrying Mulaney, Munn publicly revealed her private battle with breast cancer — a diagnosis that came in 2023 and reshaped her world. The "X-Men: Apocalypse" star shared that she had been diagnosed with bilateral luminal B breast cancer, a fast-moving and aggressive form of the disease that affected both breasts.

In an emotional interview, Munn spoke candidly about the experience. She said the diagnosis forced her to confront mortality in a way she hadn't before. "Cancer doesn't care who you are," she explained. "It comes at you, and you have no choice but to face it head-on."

Her thoughts immediately turned to her young son, Malcolm, who was just one year old at the time. While she had never been someone deeply afraid of death, the idea of leaving her child behind made the situation far more terrifying.

Within just 30 days of diagnosis, Munn underwent a series of intense medical procedures, including a lymph node dissection, a nipple delay surgery, and a double mastectomy.

She credited her doctors for guiding her through difficult choices, and said she ultimately chose procedures that gave her the best chance of preserving what she could. "I want to give myself the best shot of keeping the parts of me that I can keep," she said.

As Munn faced her breast cancer diagnosis and treatment, Mulaney stood closely by her side. In a candid reflection, Mulaney opened up about what the experience meant to him as a partner and a father.

He shared that the past few years brought significant challenges for them as a couple, saying they had navigated it all together, side by side. Throughout her diagnosis and treatment, the actor admitted to feeling both fearful and deeply protective.

John Mulaney's Wife Olivia Munn: Their Growing Family and a New Chapter

Mulaney and Munn have expanded their family in recent years, welcoming two children together. Their first child, a son named Malcolm Hiệp, was born in November 2021. More recently, the couple welcomed their second child, a daughter named Méi, via surrogate.

Their journey into parenthood marks a significant new chapter in Mulaney's life, following major personal changes. Before his relationship with Munn, Mulaney was married to artist Anna Marie Tendler.

The former couple was together for six years before announcing their separation. A representative for Mulaney confirmed the split, noting that he would not be commenting further as he focused on his recovery and return to work.

Tendler also addressed the divorce in a statement, expressing heartbreak and wishing Mulaney support and success moving forward. Since then, Mulaney's life has taken a new direction — one shaped by fatherhood, partnership, and resilience alongside his wife.
