"I am very frustrated today seeing reports that I got surgery to lose my baby weight! This is FALSE," the reality TV star, 33, tweeted. "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!!!"

She had plenty of motivation. Last month, Kardashian explained that chatter about her weight during her pregnancy "hurt my soul." After she welcomed her daughter North in June, she began following the Atkins diet and has since lost 50 pounds.

"I'm so proud of my accomplishment & NO ONE will take this away from me with fake reports!" she tweeted. "Say what u want about me but I work hard & am the most disciplined person u will ever meet!"
