Kim, Khloe and Kourtney Kardashian Sued for $5 Million in Class Action Lawsuit

Kim Kardashian and her sisters Khloe and Kourtney have been slapped with a $5 million class action lawsuit for their roles in endorsing the weight loss product QuickTrim.

The suit charges that QuickTrim is "marketed by the defendants as a clinically proven formula that will increase metabolism, curb appetite and promote weight loss. In reality, QuickTrim's main ingredient is a large dose of caffeine, which the FDA has determined is not a safe or effective treatment for weight control," the Manhattan federal court filing states according to the New York Post.

The reality TV personalities, who are renowned for endorsing countless products, have reportedly angered a number of QuickTrim consumers for what critics allege is false advertising and may be forced to pay damages if the court finds any wrong doing.

The court documents also state that QuickTrim products "generally feature ... photos of one or more of the Kardashian sisters in a bikini or other revealing attire," which some argue is deliberately misleading.

Kim, 31, and Khloe, 27, who reportedly earn anywhere up to $10 million per single tweet, have also previously tweeted about their alleged 15-pound weight loss which they both attribute to using QuickTrim, and which legal experts argue is further proof of false advertising.

The class-action lawsuit could potentially add yet another blow to the Kardashian empire, which has suffered immensely since Kim filed for divorce from NBA star Kris Humphries after just 72 days of marriage.

Viewers of their reality TV show "Keeping Up With the Kardashians" accused Kim of staging her lavish nuptials to 26-year-old Humphries for financial gain after it was reported that she had earned a substantial amount of money after selling her wedding photos, which she has denied.

In December, reports swirled linking Kardashian products to Chinese sweatshops, which resulted in further backlash with thousands of consumers uniting to boycott Kardashian products.

The Kardashian sisters have not yet addressed the pending lawsuit.
