Olivia Munn documented cancer journey for son Malcolm to watch one day in case she ‘didn’t make it’

Olivia Munn wanted to do something special for her son, Malcolm, in case she didn’t survive her scary cancer battle.

“If I didn’t make it, I wanted my son, when he got older, to know that I fought to be here, that I tried my best,” the actress, who shares the 2-year-old with partner John Mulaney, admitted on “Good Morning America” Thursday.

“You want the people in your life that maybe don’t understand what’s going on right now to know that you did everything you could to be here.”

“The Newsroom” star, 43, was diagnosed with breast cancer in April 2023.

A month later, she underwent a double mastectomy followed by four more surgeries, including a hysterectomy and hormone treatments that resulted in a medically induced menopause.

Munn publicly revealed her health news earlier this year in an emotional post shared via Instagram.

“I went from feeling completely fine one day, to waking up in a hospital bed after a 10-hour surgery the next,” she wrote at the time.

During her “GMA” appearance, the “Daily Show” alum also explained that her first thought when told of the cancer diagnosis was of her son.

“I just thought of my baby,” she shared. “Cancer, that’s the word you don’t want to hear…cancer takes down a lot of people.”

Before beginning treatment, Munn froze her eggs in hopes of still having more children one day.

“John and I had a long talk about it,” she revealed. “We realized we [weren’t] done growing our family.”

Munn was looking to retrieve only one healthy embryo but ended up with two, which made both her and the comedian, 41, burst into joyful tears.

“The Predator” star raved about Mulaney’s support on “GMA,” calling him the “best human being.” However, she did reveal one gripe.

“The one problem is he makes me laugh so much,” she adorably gushed. “Sometimes I have to tell him to leave the room … I’m literally going to pop a stitch.”

The couple began dating in 2021 following Mulaney’s divorce from his wife of six years, Anna Marie Tendler. The “Everybody’s in LA” host has been by Munn’s side throughout her cancer recovery.
