Olivia Munn: Biography, Family, Cancer & Marriage

Olivia Munn has spent nearly two decades shifting between TV host, film actress, and public advocate — never quite fitting a single box. Her journey from the G4 studio floor to a Time Women of the Year cover is marked by sharp career pivots, a very public romance and marriage, and a health disclosure that reshaped her public role.

Birth date: July 3, 1980 ·
Birthplace: Oklahoma City, Oklahoma, USA ·
Spouse: John Mulaney (married July 2024 – present) ·
Children: 2 ·
Notable work: The Newsroom, Attack of the Show! ·
Health disclosure: Breast cancer survivor (2024)

Eight key facts, one pattern: Olivia Munn’s public record is consistently documented across entertainment biographies, news outlets, and her own social media — but a few gaps remain in her early relationship timeline and custody details.

Is Olivia Munn Vietnamese or Chinese?

Olivia Munn’s ethnic background

Olivia Munn is of Chinese and Vietnamese descent. Her mother, Kimberly Schmid, was raised in Vietnam and is of Chinese ancestry, while her father is American. Biography (entertainment biography resource) describes Munn as having an American father and a Vietnamese-raised mother of Chinese descent. IMDb (film industry database) confirms her mother’s Chinese ancestry.

How she identifies culturally

Munn has publicly embraced her Asian heritage. Her Instagram bio reads: “Breast Cancer Survivor. Free test in bio saved my life. Proud Asian American.” She grew up partly in Tokyo, Japan, after her family moved around, which also shaped her multicultural identity.

The implication: Munn’s background is frequently simplified as “half-Asian,” but the specific Chinese-Vietnamese mix is well-documented by tier-2 sources, giving readers a precise answer.

Who is the father of Olivia Munn’s baby?

John Mulaney’s role

Comedian John Mulaney is the father of Olivia Munn’s two children. People (celebrity news magazine) reported that their son Malcolm Hiệp was born in November 2021. Their second child, a daughter, arrived in 2024/2025, though the exact date has not been publicly disclosed.

Relationship timeline

• First spotted together June 2021 (Wikipedia (community encyclopedia))
• Married in July 2024 in an intimate ceremony officiated by Sam Waterston (Wikipedia (community encyclopedia))
• Two children together as of 2025

This rapid shift reshaped Mulaney’s image and brought the couple into the spotlight as a unit.

What condition does Olivia Munn have?

Breast cancer diagnosis

Olivia Munn was diagnosed with breast cancer in 2023. TIME (news magazine) reported that a biopsy revealed luminal B cancer in both breasts, described as aggressive and fast-moving. She underwent a double mastectomy.

How it was detected

Munn credits a free breast cancer risk assessment tool (the Tyrer-Cuzick test) for catching the cancer early. She has since advocated strongly for others to use similar assessments. The early detection likely saved her life.

Treatment and advocacy

After surgery and treatment, Munn was declared a cancer survivor. In 2025, TIME named her one of the Women of the Year, recognizing her advocacy work.

The pattern: Munn turned a private health crisis into a public awareness campaign, using her platform to push for early detection tools that are often underutilized.

How many children does Olivia Munn have?

First child with John Mulaney

Olivia Munn and John Mulaney have two children. Their first, a son named Malcolm Hiệp, was born in November 2021 (People (celebrity news magazine)). The name “Hiệp” honors Munn’s Vietnamese heritage.

Second child arrival

In 2024 or early 2025, the couple welcomed a second child, a daughter. The exact birth date has not been publicly announced. Munn and Mulaney now have two children.

This stable family unit marks a new chapter for Munn, who balances motherhood with her ongoing career.
