Reality show star Kim Kardashian is involved in a legal battle with a diet cookie manufacturer, after reportedly branding its sweet weight loss treats "unhealthy." Kim kicked off the fight with bosses at Dr. Siegal's Cookie Diet Company, accusing them of falsely claiming she was endorsing their brand. CEO Matthew Siegal, son of the celebrity doctor behind the weight loss program, countered by filing his own lawsuit in Miami Dade County, Florida, yesterday morning, after discovering the actress used her blog to claim Dr Siegal's cookies are unhealthy. Siegal claims Kardashian had "commercial motive" for the attack because she is a spokesperson for a rival weight loss program QuickTrim. He tells "We received a letter a week ago asking us to remove a link to a news story (that we did not write) on our Web site that implied she was using and endorsing our product. And although we did this we discovered that more than a month before she had made her comments on Twitter claiming our product was 'unhealthy' while somebody also leaked a letter from her lawyers to our company to a celebrity Web site."
