Kate Hudson has recently posed in lingerie to raise money for breast cancer research.

The 42-year-old actress shared a post on Instagram wearing only a matching bra and underwear set, but it’s all in the name of advocacy, according to PEOPLE.

She captioned the post, “It’s Breast Cancer Awareness month and I’m stretching my quads before joining my friends at @kitundergarments and @thirdlove as they kick it to cancer by donating 15% of sales from the #kitstokickcancer collection to Women’s Cancer Research Fund.”

In the pic, Hudson is seen flashing her abs while wearing white heeled booties.

Hudson also shared some statistics from the Breast Cancer Research Foundation, including the fact that the research has led to a 40% reduction in breast cancer deaths in the last 25 years, according to the organization.

In her Instagram Story, Hudson left a link for people to donate to the foundation.

Hudson has also been open about her workout journey after having her daughter, Rani, 2. In January, she even shared an Instagram Story about her weight.

She wrote at the time, “So, post holiday I’m basically 136… I always round up!. I’m going to say 3-5lbs is mostly water and I’m a muscular frame so I weigh more even though I’m lean… important for people to understand that! Weight in muscle is a happy number! 10 to go” on the side.

Hudson also shared a video of herself afterward jumping on a trampoline next to the words, “rebounding 30 minutes.” In August, she shared a video doing weight-bearing squats, captioning, “All about that squat!”

She also shared a peek into her push-up and dancing bear plank routine. Hudson encouraged her followers to give the hip mobility exercise a shot, but she gave a gentle reminder, stating, “Don’t hurt yourself. Be kind to your body!!!”
