After reading the latest rumours about her, feisty Kim hit Twitter to slam the originators of the speculation for comparing her pre- and post-birth photos as the basis for the story.
Not mincing her words, a clearly annoyed Kim said: "Get a life! Using pics of me 15lbs skinnier (before I had my baby) comparing to me now! I still have weight to lose!"
33-year-old Kim continued to rant: "Anyone who has had a baby knows how hard it is to lose weight (especially the last bit of weight) and your body totally changes!"
Kim added: "I'm not perfect but I will never confirm to your skinny standards, sorry! Not me. And BTW, I've lost a lot so far and I'm proud of that! Don't give young girls a complex!"
And don't mess with Kim, it seems!
Reality star Kim became a first-time mother on 15 June when she and rapper Kanye West welcomed their daughter North West.
During her pregnancy, Kim was also faced with daily rumours about her pregnancy weight gain and figure, admitting in March 2013 she was feeling a bit self-conscious about her changing body.
"I've found that I've gained inches and I've gotten wider but my belly hasn't popped yet, so I struggle finding things that don't make me look heavy. Some days my baby bump really shows, and some days it doesn't… so I never really know what I'm going to look like," she said.
"At this stage I guess I'm more focused on concealing the weight gain than I am about dressing the bump, just because it hasn't popped yet."
Kim had plenty of support from her loyal fans, however, and from celeb pal Cheryl Cole who tweeted at her: "I think you are an incredibly beautiful woman inside and out… I can only imagine how tough it is to be heavily pregnant and feeling extremely vulnerable on top of some of the daily criticism you take."
Since giving birth to North, Kim has been working to regain her pre-pregnancy figure, posting a sexy selfie of herself in a swimsuit to Instagram in October 2013, saying it was her "big middle finger" to those who'd criticised her pregnancy shape.
She has also called losing her baby weight "the greatest challenge" of her life after gaining 50lbs while pregnant.
It's not the first time Kim has defended her famous rear from rumours: a few years ago, viewers on Keeping Up With The Kardashians saw her having a X-ray of her bottom to prove it was natural.
