Olivia Munn is in awe of Kate Middleton's strength.
More than one year after the Newsroom alum shared her breast cancer diagnosis, she gave a royally sweet shout-out to the Princess of Wales for being candid about her own cancer journey.
"What really meant a lot was to hear Princess Kate Middleton say how difficult the phase after cancer treatment is," Olivia told E! News in an exclusive interview. "Because those of us going through it understand that this second part of the journey can be really difficult and exhausting."
The 45-year-old—who shares kids Malcolm, 3, and Méi, 13 months, with husband John Mulaney, 43—emphasized that it's because having cancer is a lifelong journey.
"Before with the treatment, I knew there was like, 'OK, you have these five surgeries coming up, you've got these tests you have to do, you have this medicine you have to do,'" she explained. "Then you get to a place, you're like, 'OK, I've done it all.' And they go, "Oh yeah, but now you have to do this for the next five years. And then for the rest of your life you have to do this and you have to abstain from this.'"
And as Olivia contended with this stage in her battle, it meant so much that Kate—who hasn't shared what type of cancer she was diagnosed with—was able to so clearly articulate how emotionally complex it is for those going through it. In fact, it helped her to be able to put it into words.
"When Princess Kate said that, she said something that I had been feeling but wasn't able to articulate even to myself," the Daily Show alum reflected. "I had those same feelings, but I was just looking at it as one big journey. But she's right when she's like, there's this part and then there was the phase after that's really, really difficult. So I really, really appreciated her saying that."
As Olivia navigates the ups and downs of her health battle, she's found a much-needed slower stride. For the actress, taking walks has allowed her to decompress amid her busy schedule.
"It's only been the last couple of years that I've actually been like, 'Let me just go take a walk to breathe,'" Olivia—who married John in July 2024—admitted. "I don't think there was any time in my teens, my twenties, my thirties where I just took a walk to breathe."
"But now, after going through so much in the last few years, I really appreciate slowing down and just doing things that are really peaceful and then not being hard on myself," she added. "A win is getting the little things done, but a win is also at the end of the day, not feeling bad that I didn't get the things done."
So, joining forces with Athleta for its Celebrate the Wins holiday campaign was the perfect collab. After all, she slips on her The Clouds jacket to take baby Méi on a walk when she needs to unwind.
"We're in Chicago right now, so I'll put on my baby carrier," she explained. "I put on that coat and then I zip her up in it. We'll just go for a little walk and feel the cold air and see the Halloween decorations on people's doorsteps and then be in my thoughts walking around."
