Kim Kardashian has hit out at her followers on Twitter for branding her fat. 

The Keeping Up With The Kardashians star opened up about her struggle to shed the weight to Life & Style magazine recently and admitted that she is relying on diet supplement QuickTrim to get her body back in shake.

However, the 31-year-old was left unimpresses when one of her followers on Twitter commented on her weight gain, writing: "Kim Kardashian OMG! You are fat!"

Responding to the jibe with: "I will start QuickTrim ASAP then geez!" the star wrote.

The cruel outburst provoked Kim K's little sister, Kendell Jenner, to step in and defend her sibling, who posted a sweet message on the social networking site, saying:

"Don't listen to them you skinny princess."

It has been rumoured that Kim's rapper boyfriend, Kanye West, is also encouraging the star to lose 20 pounds so she can fit into clothes from his KW designer range - even telling his lover that Beyonce has a similiar shape but has a supermodel body.

Poor Kimmy!
