Los Angeles, Nov 21 (IANS): Reality TV star Kim Kardashian, who gave birth to daughter North West five months ago, denies reports claiming she went for reduction treatment to get rid of her baby weight.

According to Life and Style magazine, she allegedly spent more than $80,000 on stretch-mark treatments and fat-reducing ultrasound procedures to get back in shape.

Kim took it to microblogging site Twitter to deny the claims, reports contactmusic.com.

"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 and healthy, I work out so hard and this was such a challenge for me but I did it," the 33-year-old tweeted.

"I am so proud of my accomplishment and no one will take this away from me with fake reports. Say what you want about me, but I work hard and am the most disciplined person you will ever meet," she added.

Engaged to rapper Kanye West, Kim delivered their daughter June 15 at the Cedars-Sinai Medical Center here.
