John Mulaney issued a heartfelt note to his longtime partner and mother of his son, Olivia Munn, on social media after she revealed Wednesday that she has been secretly battling breast cancer.

“Thank you for fighting so hard to be here for us. Malc and I adore you. ❤️,” the comedian, 41, wrote to the “Daily Show” alum, 43, via Instagram Wednesday.

He was joined by several other celebrities who sent Munn their well-wishes, including Amanda Kloots, who wrote, “Omg Olivia. Thank you for being so brave in sharing your story with the world. You are a light and I’m sending you so much love and strength.”

“Thank you for fighting so hard to be here,” he wrote in part via Instagram.

Niecy Nash added, “I love you friend. May God continue to bless you with good health and a long happy life ❤️🙏🏾❤️🙏🏾❤️” as Kaley Cuoco chimed in, “Thank you for sharing this! Wow❤❤❤❤❤🙌🙌.”

Munn shared in a lengthy message on Instagram that she was diagnosed with breast cancer in April 2023 and had to undergo a double mastectomy.

“In the past ten months, I have had four surgeries, so many days spent in bed I can’t even count and have learned more about cancer, cancer treatment and hormones than I could have ever imagined,” she wrote.

“Surprisingly, I’ve only cried twice. I guess I haven’t felt like there was time to cry.”

Munn — who just made her red carpet debut with Mulaney in January despite dating for three years — said she allowed people to see her amid her health journey only when she had “energy” and could “get dressed and get out of the house.”

The “Predator” star then provided her followers with some helpful tips for early cancer detection.

In her emotional post, she thanked Mulaney for “being there” before each surgery and after she woke up, and placing framed photos of their 2-year-old son, Malcolm, so it would “be the first thing [she] saw” when she opened her eyes.

The couple has been dating since 2021. At the time, Mulaney was still in the midst of his divorce from his then-wife of six years, Anna Marie Tendler.

Munn said Mulaney would leave pics of Malcolm for her to see when she woke up from surgery.

Although some speculated the former “Saturday Night Live” writer began dating Munn before his marriage ended, he maintained during an appearance on “Late Night With Seth Meyers” that he “moved out” of the home he shared with Tendler, 38, in October 2020, and, by the Spring of 2021, he had “met and started to date a wonderful woman named Olivia.”

He then announced during the September 2021 show that he and Munn were expecting a baby together.

The couple has yet to get engaged or express plans to tie the knot, but often share sweet photos of their family of three on social media.
