Siegal v. Kardashian [1]

Dr. Sanford Siegal, creator of the "Cookie Diet" weight-loss program, and his company, Dr. Siegal's Direct Nutritionals, LLC, filed a defamation lawsuit against celebrity socialite, model, and actress Kim Kardashian [2] after she posted negative comments about the "Cookie Diet" on Twitter.  

The controversy began when Dr. Siegal's company placed a hyperlink on its website [3] to a third-party article that incorrectly claimed that Kardashian, among other celebrities, used the "Cookie Diet" program.  According to the complaint [4], Kardashian then posted the following comments on her Twitter page in October 2009:

14(a) Dr. Siegal's Cookie Diet is falsely promoting that I'm on this diet.  NOT TRUE!  I would never do this unhealthy diet! I do QuickTrim! . . .

14(b) If this Dr. Siegal is lying about me being on this diet, what else are they lying about?  Not cool!  . . .

The complaint alleges that these statements are false and defamatory, and that Kardashian had a "commercial motive" to defame Dr. Siegal's company because she is a paid spokesperson [5] for QuickTrim diet products.
