0 Kardashian sisters sued for $5 million

Socialite Kim Kardashian and her sisters - Khloe and Kourtney - have been sued for $5 million for allegedly making false statements about a weight-loss drug they endorse.

The trio endorses diet product QuickTrim, designed to detoxify the body and enable weight-loss.

However, four angry customers, who reportedly purchased QuickTrim because of their endorsement, have now taken legal action against the Kardashians, alleging the stars make bogus statements about the drug's effectiveness in advertisements, reports nypost.com.

A portion of the complaint reads: "In reality, QuickTrim's main ingredient is a large dose of caffeine, which the FDA (Federal Drug Administration) has determined is not a safe or effective treatment for weight control."

0 Pippa Middleton, Kardashians among "most fascinating" of 2011

NEW YORK: What do Britain's Pippa Middleton and the Kardashian family have in common?

They are all among the 10 most fascinating people of 2011, according to veteran journalist Barbara Walters.

Middleton, 28, younger sister of Prince William's new wife Kate, was named on Wednesday along with British reality TV guru Simon Cowell, singer Katy Perry and businessman Donald Trump as making the list in Walter's annual ABC TV special.

Walters will announce the number one most fascinating person of 2011 when the 90-minute show "Barbara Walters Presents the 10 Most Fascinating People of 2011" airs on December 14.

Other celebrities making up the top 10 most prominent names in entertainment, sport and pop culture include baseball star Derek Jeter, and "Modern Family" actors Eric Stonestreet and Jesse Tyler Ferguson who play a gay couple on the Emmy-winning TV comedy.

Middleton found unexpected fame during the British royal wedding in April when she wore a figure-hugging white dress as maid of honor to her sister Kate. She has been a constant fixture in U.S. and British celebrity media ever since.

Socialite sisters Kim, Khloe and Kourtney Kardashian and their mother Kris -- the biggest reality TV stars in the United States -- found new fame in 2011 when Kim held a lavish summer TV wedding after a whirlwind romance that ended in her filing for divorce just 72 days later. (Reuters)
