The Keeping Up With The Kardashians star looked rather downcast as she left her New York building on Wednesday afternoon (20 November) amid a US tabloid claim she'd had a bit of surgical help losing three stone since the birth of daughter North West in June.
Kim, 33, hit back at the allegation via a lengthy Twitter rant, saying: "I am very frustrated today seeing reports that I got surgery to lose my baby weight! This is FALSE.
"I worked so hard to train myself to eat right & healthy, I work out so hard & this was such a challenge for me but I did it!!! I'm so proud of my accomplishment & NO ONE will take this away from me with fake reports!"
Kim concluded: "Say what u want about me but I work hard & am the most disciplined person u will ever meet!"
The reality star has certainly been eager to show off her post-baby body in recent days, donning a series of skintight and revealing outfits during her stay in New York.
Yesterday was no different as she joined mum Kris Jenner for an outing wearing a purple crop top, tight grey pencil skirt and oversized cosy yellow coat.
During a US TV appearance in October, Kim revealed she'd lost more than three and a half stone since giving birth on 15 June.
"I had pre-eclampsia, so I would swell up. It's really dangerous actually so I had to deliver five weeks early. At the time I didn't know what was going on."
She added: "It was honestly the greatest challenge of my life to have gained 50lbs. Actually, I got on the scales today and it said that I am 50lbs down, and that made me really excited."
