From the meaning behind his middle name to his first birthdays and his new role as an older brother, Malcolm’s early years have included several meaningful family milestones.

As of November 11, 2026, Malcolm is four years old and approaching his fifth birthday. Here’s a closer look at Malcolm Hiệp Mulaney’s age, birthday, parents, family, early life, younger sister, and cultural background, based on information his family has made public.

Who Is Malcolm Hiệp Mulaney?
Malcolm Hiệp Mulaney is best known as the son of John Mulaney and Olivia Munn. He was born in November 2021 and made his public debut about a month later, when both parents shared photographs of their newborn on Instagram on Christmas Eve.
His parents’ careers naturally created interest in his arrival. John Mulaney is an established stand-up comedian, actor, and writer, while Olivia Munn has built a career across television and film.
Still, Malcolm shouldn’t be confused with an entertainer or public figure pursuing a career of his own. He’s a young child whose name appears in entertainment coverage because of his parents. Most reliable information about him comes directly from their interviews, public appearances, and social media posts.
Those glimpses have revealed some charming moments from his childhood, but plenty remains private. That’s an important distinction when discussing the life of a celebrity’s child.
Malcolm Hiệp Mulaney Age and Birthday
Malcolm Hiệp Mulaney was born on November 24, 2021. As of November 11, 2026, he’s four years old and just weeks away from celebrating his fifth birthday.
His late-November birthday places him under the Sagittarius zodiac sign. He was also born during the Chinese zodiac’s Year of the Ox, a connection Olivia Munn highlighted when she first introduced her son publicly and affectionately called him her “Golden Ox baby.”
Birthdays have provided Munn with opportunities to reflect on motherhood as Malcolm has grown. His first birthday was celebrated in November 2022 during a family vacation, complete with chocolate cake and a heartfelt message from his mother about the happiness he’d brought into her life.
His third birthday carried even deeper emotional meaning. Munn shared a photograph from the previous year and reflected on how Malcolm had helped her through an extraordinarily difficult period. She described the ways motherhood had made her both stronger and softer.
These posts offer more than simple birthday updates. They show how Malcolm’s milestones have become markers in his parents’ own changing lives.
Malcolm Hiệp Mulaney’s Early Life and Childhood
Malcolm’s earliest months were documented through a series of carefully shared family photographs and stories. His parents waited until Christmas Eve 2021, roughly a month after his birth, to introduce him publicly.
During his first year, Munn occasionally gave followers a glimpse of everyday life with a baby. She described Malcolm as cheerful and shared stories about his love of bath time, books, cuddling, and other ordinary childhood routines.
There were plenty of playful moments as well. His parents photographed him spending time with his father, enjoying tummy time, going for walks, and meeting members of their extended family.
In April 2022, Malcolm experienced his first restaurant outing when his parents took him along for pho. The moment became another lighthearted family memory shared publicly.
As he’s grown older, however, many details of Malcolm’s daily life have remained outside the spotlight. His parents haven’t publicly documented his education or routine in detail, and there isn’t reliable information available about those private parts of his childhood.
Who Are Malcolm Hiệp Mulaney’s Parents?
Malcolm’s parents, John Mulaney and Olivia Munn, were both well-established in entertainment before becoming parents.
Their careers are very different, but each has spoken publicly about how family life changed their perspective.
John Mulaney: Malcolm’s Father
John Mulaney is an American comedian, writer, and actor whose career includes acclaimed stand-up specials and writing for Saturday Night Live.
His comedy has long drawn on personal observations, relationships, and everyday experiences. Not surprisingly, fatherhood has gradually become part of that storytelling.
Mulaney has discussed parenting with his characteristic humor, often finding comedy in the unpredictable behavior of young children. Behind those jokes, though, Munn’s own accounts describe a father closely involved in Malcolm’s everyday care.
That became especially evident during Munn’s breast cancer treatment, when Mulaney balanced caring for their young son with supporting her through surgeries and hospital visits.
Olivia Munn: Malcolm’s Mother
Olivia Munn is an American actress and television personality whose credits include The Newsroom, X-Men: Apocalypse, and numerous other film and television projects.
In recent years, she’s also spoken candidly about motherhood and her experience with breast cancer.
Her public reflections on Malcolm tend to focus on the emotional side of parenting: the joy he brought into her life, the strength she found during illness, and the difficulty of temporarily being unable to care for him physically after surgery.
Together, those accounts provide some of the clearest firsthand insight into Malcolm’s early family life.
How John Mulaney and Olivia Munn Started Their Family
John Mulaney and Olivia Munn’s relationship became public in 2021. That September, Mulaney announced during an appearance on Late Night with Seth Meyers that the couple were expecting a baby.
Malcolm arrived two months later.
Years afterward, Munn offered additional context about that period. Speaking to GQ in 2024, she said she and Mulaney were still getting to know one another when she became pregnant. Their initial conversations centered on how Mulaney would be involved in their child’s life rather than on an immediate plan for marriage.
Before Malcolm’s birth, however, they decided to raise him together as a couple.
Their relationship continued to develop over the following years. In July 2024, they married during a small ceremony at a friend’s home in New York. Actor Sam Waterston officiated, and Malcolm was among the very few people present.
The family changed again only a couple of months later with the arrival of Malcolm’s younger sister, Méi June.
The Meaning Behind Malcolm Hiệp Mulaney’s Name
One of the most personal details about Malcolm is the story behind his middle name.
Olivia Munn chose Hiệp in honor of her great-uncle, Vinh Hiệp Luong. Rather than simply selecting a traditional family name, she gave her son a direct connection to someone important in her own life.
That connection became particularly visible in May 2022, when Munn shared photographs of baby Malcolm meeting his great-uncle. She explained that Malcolm’s middle name had been chosen after him.
The story adds another layer to Malcolm’s family background. His name isn’t merely connected to celebrity parents; it also reaches back into his mother’s Vietnamese family heritage and links him to an older generation.
Munn’s references to his Chinese zodiac year add another cultural dimension. When she called him her “Golden Ox baby,” she was acknowledging his birth during the Year of the Ox.
When discussing the name Hiệp itself, it’s best to stay with Munn’s confirmed explanation rather than assigning Malcolm’s middle name a meaning his family hasn’t publicly specified.
Malcolm Hiệp Mulaney’s Relationship With His Father
John Mulaney’s relationship with Malcolm has appeared in photographs and stories from almost the beginning.
Some of the sweetest early images showed Mulaney carrying his son, taking walks with him, playing at home, or simply holding him while Malcolm studied his father’s face.
A particularly memorable father-son moment came in February 2022. Malcolm visited Saturday Night Live while Mulaney was preparing to host the show. Munn shared backstage photographs from the visit, giving fans a glimpse of Malcolm stepping into his father’s professional world while still an infant.
More serious circumstances later highlighted Mulaney’s role as a parent.
During Munn’s cancer treatment, she described him moving between family responsibilities and hospital visits. He cared for Malcolm, took him to the park, handled naps and bedtime, and continued supporting Munn throughout her treatment.
Those accounts offer a fuller picture of their father-son relationship than photographs alone can provide.
Malcolm Hiệp Mulaney’s Special Bond With Olivia Munn
Munn’s descriptions of Malcolm have consistently shown how profoundly motherhood has affected her.
That bond took on additional significance after she was diagnosed with breast cancer in 2023, a diagnosis she publicly revealed in March 2024.
Her treatment included multiple surgeries, including a double mastectomy. Recovery temporarily changed what she could physically do as a mother.
Munn recalled returning home after surgery and having Malcolm ask to be picked up. She couldn’t safely lift him, so she crouched down to hug him instead. For a parent accustomed to holding her child, the moment was particularly painful.
At the same time, Malcolm offered an emotional refuge. Munn has explained that being with him allowed her mind to move away from illness for a while.
She also documented parts of her cancer experience with her son in mind. If the worst happened, she wanted him to know one day that she’d fought to remain with him.
It’s one of the most personal parts of Malcolm’s story and helps explain why Munn’s birthday messages about her son often carry such emotional weight.
Does Malcolm Hiệp Mulaney Have a Sister?
Malcolm has one younger sibling, Méi June Mulaney.
Méi was born through gestational surrogacy on September 14, 2024, making Malcolm a big brother shortly before his third birthday.
His adjustment to having a newborn sister produced one of John Mulaney’s funniest parenting stories. Mulaney explained that Méi initially didn’t do much besides make typical newborn sounds, and Malcolm seemed to think she might be a toy. When she squeaked, he apparently wondered how he could make her do it again.
Eventually, Mulaney said, Malcolm began to understand that his sister was a little girl rather than a new object in the house.
Méi’s name carries family significance of its own. Méi, pronounced “May,” means plum in Chinese. June, meanwhile, has a connection to Olivia Munn’s mother, Jung. Mulaney has explained that June was considered as their daughter’s first name before the couple ultimately chose Méi June.
Together, Malcolm and Méi’s names reflect the family’s interest in honoring cultural and family connections.
Malcolm Hiệp Mulaney’s Childhood Milestones
Several of Malcolm’s early milestones have been documented publicly, beginning with his Christmas Eve introduction in 2021.
As his first year unfolded, his parents shared occasional updates about his development. By October 2022, Munn said he was learning to speak. She later showed him repeating words from a Mandarin children’s book given to him by comedian Ali Wong.
That language-learning experience is particularly noteworthy because it connects an ordinary developmental milestone with his mother’s desire to introduce him to part of his family’s cultural heritage.
His first birthday followed in November 2022. Other milestones came as the family itself changed.
In July 2024, Malcolm attended his parents’ intimate wedding. Two months later, Méi’s birth gave him an entirely new role as an older brother.
Taken together, these moments create a useful timeline of his early years without requiring speculation about the parts of his childhood his parents have kept private.
Malcolm Hiệp Mulaney’s Cultural Background and Family Heritage
Family heritage has appeared repeatedly in the stories Munn and Mulaney tell about their children.
Munn has Chinese and Vietnamese family roots, while Mulaney comes from an Irish American family background. Malcolm therefore grows up with connections to several family traditions.
Some of those connections are visible in his name. Hiệp honors his mother’s Vietnamese great-uncle, while Munn has also introduced Malcolm to Mandarin through children’s books.
The family’s references to the Chinese zodiac provide another example. Malcolm was celebrated as a Year of the Ox baby, while Méi’s 2024 arrival occurred during the Year of the Dragon.
Mulaney has also spoken warmly about becoming part of Munn’s extended Vietnamese family and the closeness he experienced within that family environment.
Still, it’s worth making an important distinction. Family ancestry and traditions can be documented, but Malcolm’s own sense of cultural identity is personal and will develop as he grows. It shouldn’t be defined for him by outside observers.
How Olivia Munn’s Health Journey Affected Family Life
Munn’s breast cancer diagnosis became one of the most difficult periods in the family’s story.
She was diagnosed in 2023 and revealed the diagnosis publicly the following year. Her treatment involved multiple surgeries, including a double mastectomy, and required significant physical and emotional recovery.
For a household with a young child, that meant ordinary family routines had to change.
Mulaney took on extensive parenting responsibilities while continuing to support Munn. According to her account, his days could involve caring for Malcolm, taking him to the park, getting him down for a nap, traveling to the hospital to see her, returning home for bedtime, and then going back to the hospital.
For Munn, motherhood also shaped the way she processed her diagnosis.
She wanted Malcolm to know, if he ever had to look back on that period without her, that she’d fought as hard as possible to stay in his life.
Fortunately, the story she has publicly shared isn’t only about illness. It’s also about a family adapting to a frightening situation and supporting one another through it.
Sweet Family Moments and Life Away From the Spotlight
Many of the stories surrounding Malcolm aren’t dramatic at all, and that’s part of their charm.
As a baby, he wore mittens knitted by his grandmother. He went on walks with his father, spent time with relatives, enjoyed his first restaurant visit, and appeared in playful family photographs.
His parents’ social circle occasionally entered those childhood memories as well. Malcolm had an early playdate with Henry Golding’s daughter Lyla, and Pete Davidson visited him when he was still a baby.
Yet these snapshots shouldn’t be mistaken for a complete record of Malcolm’s life.
His parents share selected moments, not every detail. Information about his schooling, private friendships, daily schedule, and many other aspects of childhood hasn’t been publicly established.
That privacy matters. Malcolm may have famous parents, but he’s still a child rather than a public personality responsible for maintaining an audience.
Interesting Facts About Malcolm Hiệp Mulaney
A handful of details help bring Malcolm’s family story together.
He was born during the Chinese Year of the Ox and publicly introduced on Christmas Eve 2021. His middle name honors Olivia Munn’s great-uncle, connecting him directly to his mother’s Vietnamese family heritage.
Before his first birthday, he’d already visited the Saturday Night Live set while his father was hosting and had experienced his first family restaurant outing.
As he grew, Munn introduced him to Mandarin-language books, and he began repeating words while learning to speak.
Another major family milestone came in 2024. Malcolm attended his parents’ private July wedding and became an older brother just two months later when Méi was born.
These aren’t extraordinary achievements, nor should they be presented that way. Their value comes from the picture they create of Malcolm’s early family life and the traditions surrounding him.
Malcolm Hiệp Mulaney’s Family Timeline
Malcolm’s story begins on November 24, 2021, when he was born to John Mulaney and Olivia Munn.
His parents introduced him publicly on Christmas Eve that year. Throughout 2022, they shared occasional updates as he reached early developmental milestones, met relatives, began learning to speak, and celebrated his first birthday.
Family life became more challenging after Munn’s breast cancer diagnosis in 2023. Her treatment and recovery continued while Malcolm was still very young, requiring both parents to adjust their routines.
The following year brought major changes of a happier kind.
Munn and Mulaney married in July 2024 with Malcolm present at the intimate ceremony. Méi June arrived on September 14, making him a big brother.
The parents continued discussing selected aspects of family life in interviews during 2025 and beyond. By November 2026, Méi had turned two, while Malcolm was approaching his fifth birthday.
Final Thoughts
Malcolm Hiệp Mulaney’s story is, at its heart, less about celebrity than family.
Born in November 2021, he’s spent his earliest years surrounded by parents who have occasionally invited the public into their family life while keeping many personal details private. The moments they’ve shared range from funny first experiences and birthday celebrations to much more difficult memories from Olivia Munn’s cancer treatment.
His name itself tells part of that family story. Hiệp honors a beloved relative and connects Malcolm to his mother’s Vietnamese heritage. His exposure to Mandarin and the family’s celebration of Chinese zodiac traditions add further cultural connections to his childhood.
The arrival of Méi June in 2024 added another dimension, turning Malcolm from an only child into an older brother. That same year, he watched his parents marry during an intimate ceremony.
As of November 2026, Malcolm Hiệp Mulaney is four years old and preparing to celebrate his fifth birthday. There will naturally be continued interest in the son of John Mulaney and Olivia Munn, but the most accurate way to understand his life is through the information his family has chosen to make public.
For now, those stories paint a warm picture: a young boy growing up amid humor, cultural traditions, difficult challenges, close family relationships, and plenty of affection.
