Kardashian sisters respond to lawsuit

Kim Kardashian and her reality star sisters have taken legal action in a bid to have their names removed from a $5 million lawsuit.

Kim, Khloe and Kourtney Kardashian serve as the celebrity spokesmodels for diet regimen QuickTrim, a range of products designed to detoxify the body and promote weight-loss.

Four angry customers, who reportedly purchased QuickTrim because of the trio's endorsement, filed legal papers against the Kardashians in New York in March (12), alleging the stars made bogus statements about the drug's effectiveness in advertisements for the products.

The stars have now lodged their own legal documents to have their names dismissed from the suit, insisting they are merely spokespeople for the product and are not responsible for any alleged false advertising, according to celebrity website TMZ.com.
