Kim Kardashian recently showed off her skinny post-baby waist, prompting more plastic surgery rumors. Though the "Keeping Up With the Kardashians" star is facing speculation, she denied ever going under the knife to lost weight after North West's birth. 

According to E! Online, the reality TV starlet and new mom, 33, is sick and tired of negative comments about her body. 

Kanye West's fiance took to Twitter to address the talk that her post-baby body is back in tip-top shape because of a cosmetic procedure. 

"I am very frustrated today seeing reports that I got surgery to lose my baby weight! This is FALSE," tweeted Kardashian. "I worked so hard to train myself to eat right & healthy, I worked 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!"

But her rant didn't end there, for Khloe and Kourtney Kardashian's sister had more to get off her chest.

"Say what u want about me but I work hard & am the most disciplined person u will ever meet!," posted Kardashian. 

In recent weeks, tons of stories have been circulating about just how Kris Jenner's daughter dropped the weight. Kardashian had finally revealed that she had lost 50 pounds since having her daughter during a guest appearance on "The Tonight Show With Jay Leno" in October.

Kylie and Kendall Jenner's older sister had credited the Atkins diet and consistent workouts for her success. But she took the oppportunity to also express that all of the criticism directed at her weight while she was pregnant "really affected" her.

It really hurt my soul," said Kardashian. "There were these stories where I was, like, 200 pounds. I was gaining weight because I was pregnant and it was really hard to read all these stories and hear all these nasty things." 

But it looks like Lamar Odom's sister-in-law has rebounded after the hateful comments, showing off her new slimmer figure during red carpet appearances, fashion shows, and in her fiance's new "Bound 2" music video.
