'He did it all happily': Olivia Munn details partner John Mulaney's relentless support during her cancer battle

LOS ANGELES, CALIFORNIA: Olivia Munn has been on a daunting journey following her postpartum struggles and breast cancer diagnosis but she found unwavering support from her partner John Mulaney.

Speaking to People, Munn opened up about her challenging experience, sharing how Mulaney stood by her side as she underwent four surgeries including a double mastectomy.

Olivia Munn calls John Mulaney a 'hands-on father'

Munn, who was diagnosed with bilateral breast cancer diagnosis in April 2023 said, "It would've felt like climbing an iceberg without him."

The actress took a gene test in 2023 which also included Breast Cancer Risk Assessment and she tested negative at first.

However, she was later diagnosed with cancer after her OB-GYN, Dr Thais Aliabadi, calculated her breast cancer risk assessment score.

Throughout her recovery, Mulaney took on the role of a dedicated caregiver for their now two-year-old son Malcolm.

“I don't think that he had a moment to himself this past year between being an incredibly hands-on father to Malcolm and then going to and from the hospital,” Munn shared.

“I mean, this is what John's life was like, truly, through four surgeries over 10 months," the 'X-Men' actress recalled how Mulaney was a "hands-on" father.

"He was literally taking Malcolm to the park, to music class, coming home, giving him lunch, putting him to nap, driving over to Cedars Sinai, hanging out with me, bringing me food, going back home, playing with Malcolm, putting him to bed, coming back to Cedar Sinai…And then he's got his work," she said.

“I mean, there really wasn't a moment for him to really relax and breathe. And he did it all happily," she added.

Olivia Munn recalls how John Mulaney made her 'laugh too hard' during her challenging journey

Despite the challenges, Munn acknowledged the humor her partner brought into their lives during difficult times.

However, the comedic talents of Mulaney, whose show 'Everybody's in LA' is set to stream on Netflix on May 3, posed a challenge, especially during her post-surgery phase.

“It’s the best except when you’re just out of surgery and it hurts to move or even laugh,” said Munn.

“I made him leave the room a few times because he would make me laugh too hard," she added.

Elsewhere in her conversation with People, Munn said, “When we’re together, even in the midst of something painful and scary, we have so many happy days. We’re a really strong little family.”
