Kim Kardashian is sued by Dr. Siegel's Cookie Diet Company. In a legal paper filed in Miami Dade County, Florida on December 29, the manufacturer are seeking for unspecified damages against the TV personality, claiming she has falsely called their product "unhealthy" on her Twitter page.

In addition, the diet cookie company also accuse that the "Keeping Up with the Kardashians" star has a "commercial motive" behind her statement on Twitter. They come to such allegation due to the fact that Kim is a spokesperson for a rival weight loss program QuickTrim.

Prior to the Twitter lawsuit, Kim Kardashian released a cease and desist letter to the cookie maker for falsely claiming that she was endorsing their brand. "We received a letter a week ago asking us to remove a link to a news story (that we did not write) on our website that implied she was using and endorsing our product," the company's CEO Matthew Siegal told Radar Online.

"We felt betrayed by the leaking of this letter and my father Dr Siegal, who invented the product 35 years ago, was personally offended by her claims. My message to Kim Kardashian is that we have no animosity against her personally but that she should act more responsibly and not say false statements about our brand while endorsing another one at the same time."Kim Kardashian herself was previously revealed to have pocketed $10,000 from advertisers for a tweet promoting their products to her over two million followers on the micro-blogging site.
