The gorgeous actress told ITV's Lorraine that searching for her own name online would only bring trouble as it's human nature to focus on negative comments rather than good ones.
"I think if you Google yourself you're basically asking for someone to say something nasty about you or to find something," she said.
"And I think it's human nature if you read 12 nice things and then one person says something horrible that you actually secretly agree with, you might as well just not ask or just ask people who you like, who like you."
Kate also spoke about social media and how her daughter Lily, 16, is growing up in a very different world to the one she grew up in; a world that means teenagers get an idea of what it's like to be famous and talked about.
"I think it's tough. I have to say I think being a teenager in this sort of era, with social media, is about the closest thing to being a celebrity as is possible to so she sort of gets a double whammy," she explained.
"I think being commented on and sort of deconstructed and you know objectified is a horrible experience and that's why all actors and actresses are insane because it shouldn't happen to people but it does happen to teenagers like mad so we have that point of contact and luckily we are all fairly normal, we don't have gold bathtubs or anything."
Kate can next be seen alongside Cara Delevingne in thriller The Face of an Angel.
