Serena Williams laid herself bare in her latest post.
The Wimbledon tennis champ stripped off on the official Serena Williams Instagram page on Sunday.
New mum Serena, 37, admitted she was out of her “comfort zone” as she stripped topless for a breast cancer awareness campaign.
Crossing her arms over her chest in the clip, Serena sang a rendition of I Touch Myself by rock bank the Divinyls.
The powerful campaign is in aid of raising money for Breast Cancer Network Australia – and to encourage women doc regular check themselves for signs of the disease.
Serena looked sensational in the video, as in-keeping with her lack of clothes, Serena also completely ditched the makeup, allowing her natural beauty to shine through.
The sportswoman – who is married to Reddit founder Alexis Ohanian – revealed all about her involvement in the campaign in a caption accompanying the video.
She wrote: “This Breast Cancer Awareness Month I’ve recorded a version of The Divinyls global hit ‘I Touch Myself’ to remind women to self-check regularly.
“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 colours, all around the world.
“Early detection is key – it saves so many lives. I just hope this helps to remind women of that.
“The music video is part of the I Touch Myself Project which was created in honour 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.
Fans flocked to praise Serena on the powerful message she was promoting.
One follower said: “You are an inspiration! I’m 56 years old and find myself in awe of confidence and vulnerability-and your strength and passion. Keep going.”
While another continued: “Yes, great job.”
A third added: “This is so beautiful and so precious.”
