Ozzy Osbourne's daughter was bullied as a youngster and she has shared her experiences in the U.K. version of Glamour to help readers struggling with similar issues.
The reality TV star also shares her advice for feeling confident and beautiful, admitting she rarely wears a bikini as she prefers to cover up in the sun.
Osbourne offers, "Women are so unforgiving of themselves. We don't recognise our own beauty, because we're too busy comparing ourselves to other people... 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."
