However, the 29-year-old singer says starring in Netflix comedy show 'Glow' - in which she portrays Rhonda - made her learn to feel "empowered" as the focus wasn't on her looks.
She told The Independent newspaper: "On the show, we have a purpose that isn't just to look good, it's to learn to wrestle and run the ropes. On set, I was pushing myself physically, doing things I never expected I could do. It empowered me, and I feel very confident and assertive."
Kate says the perception of women is changing and girls feel confident enough to speak their minds and exercise feminism.
She explained: "Everything's slightly different now because feminism is now front and centre. It's mainstream. There are still s**t magazines that will look at women's bodies.
But I've seen reactions from influencers, and if someone talks about a women and the way she looks, women jump in like 'no, you can't f***ing say that. What's it to do with you?'
Women are being more accepted and there's more awareness of people's sexuality, gender, race and other issues in the world."
