Using a side-by-side comparison of an unedited photo of her and a cover of her on an American magazine cover, Kim showed how tabloid magazines can photo shop everything from body shape to the colour of her clothes.
And, understandably, Kim, 33, wasn't happy about it:
“BTW tabloid...please don't photoshop my clothes! If they photoshop my clothes who knows what else they tweak."
“Making fun of me pregnant & making fun of me trying to lose weight now shame on you. I'm not perfect but I will never conform to your skinny standards sorry!”
“And BTW I've lost a lot so far & I'm proud of that! Don't give young girls a complex!”
It wasn't the only bone she had to pick with the tabloids; she was also unhappy with them for making up "nonsense" about the mum-of-one undergoing butt implants.
“I'm seeing all these nonsense tabloids claiming I have butt implants-injections. Get a life!” she tweeted angrily.
Kim went on to defend her body and explained she’s still working to lose the excess fat she gained during her pregnancy with daughter North - and working to lose it slowly, without help from a plastic surgeon.
“I still have weight to lose. Anyone who has had a baby knows how hard it is to lose weight (especially the last bit of weight) & your body totally changes!”
It's nice to see Kim Kardashian speaking up on behalf of mums everywhere, isn't it?
