The 24-year-old star appeared on the cover of Style magazine for the campaign, which helps women talk about their bodies more openly.
"I am so happy with this cover and thrilled to be helping raise awareness for a cause that is so important," she wrote on Instagram sharing her cover photo.
It was started by a group of British women in response to research that shows maximum number of women feel embarrassed to go to doctors with gynaecological concerns or even speak to a friend about them.
