January Jones wants you to "love your melons!"

The Mad Men star took to Instagram on Wednesday to share a topless selfie for a good cause. Jones, wearing noting but a few necklaces and a scarecrow filter over her face, smiled wide for the camera while covering her breasts in the pic, which she posted in honor of Breast Cancer Awareness Month.

"It’s breast cancer awareness month gals and guys! This is a friendly reminder to get a mammogram!" she wrote alongside the pic.

Jones isn't the only one making a big statement to promote breast health. On Saturday, Serena Williams debuted a music video in which she sang "I Touch Myself" topless to encourage fans to check themselves for possible lumps.

"Yes, this put me out of my comfort zone, but I wanted to do it because it’s an issue that affects all women of all colors, all around the world. Early detection is key - it saves so many lives. I just hope this helps to remind women of that," Williams wrote on Instagram. "The music video is part of the I Touch Myself Project which was created in honor of celebrated diva, Chrissy Amphlett, who passed away from breast cancer, and who gave us her hit song to remind women to put their health first. The project is proudly supported by @BerleiAus for Breast Cancer Network Australia."
