Kim Kardashian

Kim Kardashian's tweeting may have landed her in bit of trouble. Dr. Sanford Siegal, the creator of the Cookie Diet, has sued Kardashian, claiming she defamed him on Twitter.

According to a release from Siegal, the Keeping Up with the Kardashians star tweeted in October that he was "falsely promoting" that she was on the cookie diet. "Not true! I would never do this unhealthy diet! I do QuickTrim!" Kardashian allegedly said via Twitter. "If this Dr. Siegal is lying about me being on this diet, what else are they lying about? Not cool!"

Last week, Siegal filed a claim in a Florida state court claiming the statements are false and defamatory. He also alleges that Kardashian was on QuickTrim's payroll when she posted the tweet.

Kardashian's tweet appears to stem from an article on CookieDiet.com, a site with no connection to Siegal, that named Kardashian as one of many celebrities who saw positive results on the diet. Kardashian sent a cease-and-desist order to Siegal, demanding the link be removed.
