Kim Kardashian, Sisters Slapped with $5 Million Lawsuit by Angry Quicktrim Customers

The famous Kardashian sisters have landed in trouble after endorsing a weight-loss pill and making false claims about it.

The unsatisfied users of the pill have filed a $5 million lawsuit against Kim Kardashian and her sisters, Khloe and Kourtne.

The Kardashians, who are undoubtedly in great shape themselves, were slapped the complaint by four angry customers who say they bought QuickTrim products due to the endorsements by the sisters, reports nypost.com.

The Manhattan federal court filing says 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 suit charges, according to the report.

The Kardashians' comment was not available.
