Kim Kardashian has slammed reports she had implants or injections to accentuate her derriere.

The reality star's changing figure was often the topic of tabloid fodder throughout her pregnancy and it seems the rumours won't stop more than eight months after giving birth.

Kardashian, 33, took to Twitter to address the latest reports she has had cosmetic surgery on her rear, as suggested by several gossip magazines recently.

"I'm seeing all these nonsense tabloids claiming I have butt implants-injections. Get a life! Using pics of me 15lbs skinnier (before I had my baby) comparing to me now!," she wrote.

"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!

"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! Not me."

Kardashian ended the post by saying how proud she was of the weight she lad lost so far, adding: "Don't give young girls a complex!"

Last year the new mother famously posted a racy snap to social media wearing a revealing white swimsuit, which she later said was her revenge on the critics who called her fat during her pregnancy.
