The 44-year-old actress had admitted she no longer feels concerned about people's "perceptions" of her, and feels "blessed" to be able to say she doesn't care what people think about her because she "likes herself".

She said: "It's a blessing to be liberated from the chains of other people's perceptions of you. It's part of wellness, working at that. I've gotten to a point where I like myself. I do my best as a person. I also have nothing to hide."

And the 'Iron Man 3' actress - who has children Apple, 12, and Moses, 10, with her former husband Chris Martin - says the trick to not being affected by people's criticisms is to not have any "judgements about yourself."

She added: "When someone doesn't like something you do, or doesn't share your interest in something, that doesn't have anything to do with you. One of the best things someone ever said to me was that the only time criticism hurts is if you have a judgment about yourself about that very thing. If someone's like, 'You d**k, you have red hair!' and you've got brown hair, it doesn't bother you."

To keep her mind off her critics, Gwyneth exercises regularly, as she says this is when she "feels [her] best."

She told Women's Health magazine: "I like feeling good, and I know I feel my best when I exercise. But it depends on the day--I definitely don't always feel like doing it. I've made it a habit, just like brushing your teeth. That's how you have to look at it. I've been a Tracy Anderson fanatic for over a decade, I'm an investor in her company, so yeah, I go every morning. I drop the kids at school, work out, go to work."
