Socialite Kim Kardashian has been slapped with a defamation lawsuit by the man behind ‘Dr Siegel’s Cookie Diet’. Dr Sanford Siegel has claimed that the reality star defamed him by calling the Cookie Diet ‘unhealthy’ on her Twitter page, reports TMZ.



In the suit, he has alleged that Kim had “commercial motive” for the attack because she’s a spokesperson for a rival weight-loss program, QuickTrim. The Cookie Doc is suing Kardashian for unspecified damages.
