Reality-TV stars Kim, Khloe and Kourtney Kardashian are being sued by a group of New Yorkers who claim there's no possible way a diet pill called QuickTrim could have helped the sisters lose weight.

According to the $5 million class-action lawsuit, the sisters, who serve as celebrity spokespeople for QuickTrim, waged a campaign of lies when they claimed the diet pill helped them get their rock hard bikini bodies because the main ingredient is caffeine.  "The FDA has determined [caffeine] is not a safe or effective treatment for weight control," notes the filing.

The plaintiffs claim they would never have purchased the QuickTrim products if they had known the truth. Rather, they claim they were misled for years by the unsubstantiated lies put out by the sisters through commercials, magazines and social media, including a tweet on Twitter by Kim that said, "Our QuickTrim cleanse will be massive! Khloe has already lost so much weight."

Remarkably, media reports indicate that the Kardashian camp is silent on the issue.
