The 'Fashion Police' host thinks there is too much pressure on beautiful women to maintain their looks and thinks it is important for everyone to stop comparing themselves to other people.
She said: ''Women are so unforgiving of themselves. We don't recognise our own beauty, because we're too busy comparing ourselves to other people. No, we are not all Gisele Bundchen or Beyonce Knowles but I can tell you even the most beautiful girls in the world have felt insecure.
''Just seeing the pressure my friends Kim Kardashian and Kate Moss are under makes me never want to be the prettiest in the room. There is no such thing as perfection.
''Try this; look in the mirror. Find one thing you like... think, 'Well, I've got this, and a lot of people don't.' You have to look at what you do have.''
Kelly famously shed 70lbs after competing on 'Dancing With The Stars' but she still doesn't consider herself to be skinny.
She told Britain's Glamour magazine: ''I call myself an FFP - former fat person. And when you're an FFP, you will always see in yourself what people used to bully you for.
''I grew up on the road with my father but I came from a very, very small village where everyone called me Kelly Smelly with the Big Belly Whose Dad's on Telly. It hurt me so badly to be judged like that.
''Even now, I don't consider myself skinny.''
