Kim Kardashian: 'I haven`t had plastic surgery'

The 30-year-old reality star, who shares her workout tips with the US fitness magazine Self, insists that her looks are God-given.

She says: 'Rumours don't bother me anymore. I've read that I've had my lips done. I've always had big lips. Look at my baby pictures. It's ridiculous.

'Or they'll show one picture of me today and one tomorrow and say I've had my nose done in between. When? Didn't you see me yesterday?”

She adds: 'And how many times have I 'had my butt done'? People's logic is so weird. I don't know why they bother! You can't worry about all the gossip.'

But the naturally curvy star admits that she has to work hard to stay in shape and that there are some things about her body that she accepts will never be perfect.

'Of course I struggle with insecure moments,' she says. 'I wish I didn't. But I love to eat! Especially sweets.

'And I'll say it. I think my thighs are jiggly and I have cellulite. Now let's move on!'
