Olivia Munn strips naked for a good cause.

The 44-year-old Newsroom actress stars in the latest advertising campaign for Kim Kardashian's Skims, modeling a selection of the brand's best-sellers – including the viral Skims push-up bra with built-in nipples.

In the photos, Munn poses in the Ultimate Nipple Bra ($64) and the Ultimate Teardrop Push-Up Bra ($60), and shows off a scar from her double mastectomy and breast reconstruction in one shot, where her chest is bare.

“It is an honor to partner with Skims and Susan G. Komen on this incredible campaign. “This cause is very close to my heart and I'm proud to help raise awareness and talk about it,” Munn said in a press release from Skims, which will own 10% of BH sales between Oct. 23 and Oct. 31. Sales donated to the charity.

“Skims’ commitment to empowerment and community fits perfectly with this campaign’s message of confidence, comfort and feeling your best self. That’s exactly how I felt when I shot this,” she added.

On Instagram, where she shared her photoshoot, Munn wrote, “During this latest shoot for the @Skims bra campaign, I decided I was tired of worrying about my mastectomy scars. Every mark that life has left in my body is proof of how hard I fought. I hope other women who are aware of their scars see this photo and feel all the love I send.”

Munn bravely shared her battle with breast cancer earlier this year, revealing that she underwent treatment and several subsequent surgeries after being diagnosed in April 2023.

Shortly after, she opened up about trying to hide her “battle wounds” on the red carpet before the public knew what she was struggling with in private.

“I have a few indentations and dents on one side of my body, near the lymph nodes, and they really needed to be dug out,” she said in an interview at the time. “And I wore some dresses on the red carpet that made me a little stressed at times.”

In a later podcast appearance, she also talked about seeing her body for the first time after the double mastectomy before getting her permanent implants.

“I was alone in my bathroom, looking at her and crying in a way I've never cried in my life,” she said. “I cried. I was devastated. I didn't recognize myself.”

“I didn't want to have big breasts,” Munn said of the replacement implants, which had to be larger because doctors removed so much tissue.

“You think, 'I'm here.' All I care about is being alive and being there for my baby. But that being said, one day people will forget or won't know, or maybe I'll never tell people I had cancer, but they'll look at me and say, “Oh, what a bad boob job.” Oh, see her to you.'”

Before her treatment, which included a hysterectomy, the star froze embryos with her now-husband John Mulaney, with whom she shares son Malcolm. The couple welcomed a daughter, Méi, via surrogate last month.
