Kate Hudson believes women are "programmed" to think they're not good enough.
The 36-year-old actress thinks girls are "highly scrutinised" but doesn't believe it is right as beauty is "subjective".
She said: "I think women are programmed to not feel that great about ourselves. Our bodies are constantly telling us that we're not good enough. And I think that's because we're so highly scrutinised - our image, our beauty or the idea of beauty - whatever that is because I believe it's subjective."
The 'Bride Wars' star insists it is important for women to "support" each other, which is something she has learned from her mother Goldie Hawn.
She told The Independent's Radar magazine: "We need to stop scrutinising each other and start supporting that we're all on this trajectory together of youth into womanhood into getting older and what's really going to shine and feel healthy and live longer is feeling good about ourselves.
"I got that from my mom because she's always been that way, so I want to encourage girls to feel good about themselves, no matter what their sizes are, and to feel motivated to be healthy and strong."
