Olivia Munn shows off her mastectomy scar in SKIMS campaign.

Olivia Munn stars in a new campaign for SKIMS.

The actress posed in the brand's underwear, topless and showing off her mastectomy scar after a battle with breast cancer.

Sharing the campaign on Instagram, Munn shared an inspiring message.

“Kintsugi” is a Japanese art form in which cracks in ceramics are repaired by filling them with gold to make objects look more beautiful.

“During this latest @SKIMS campaign shoot, I decided to stop worrying about my mastectomy scar. Every scar life has left on my body is proof of how hard I fought. I hope that other women who are self-conscious about their scars will look at these photos and feel all the love I am sending them.” [She also thanked SKIMS for donating 10 percent of the proceeds from bras sold between October 23 and October 31 to Susan G. Komen, an organization that funds breast cancer research and provides community health outreach, advocacy, and programs.

Celebrities such as Amy Schumer, Lily Aldridge, and Rachel Zoe congratulated Moon on the campaign and her powerful message.

In a promotional video for the campaign, the mother of two said, “Someone said these words to me, and they meant so much to me, and they really touched me. When it comes to breast cancer, people say, 'Welcome to the worst club with the best members'”

. [My name is Olivia Mann and I am a breast cancer survivor. When I look at my scars, the way my breasts look, and the way my clothes fit, I am just so grateful. How my body looks is a reflection of how hard I fought.”

Munn shared her breast cancer diagnosis with her fans in March and was immediately met with a wave of love and support from her community.

Happily, the New Girl actress gave birth to her second child with John Mullaney in September. The couple also share a son, Malcolm (2),

and are expecting their second child together.
