AceShowbiz - The Kardashian sisters are facing a $75 million lawsuit over allegations they breached a contract by distancing themselves from a controversial credit card scheme aimed at kids. Kim Kardashian, Khloe and Kourtney fronted the Kardashian Prepaid MasterCard, which allowed parents to give their children a small amount of credit so they can keep track of their finances.

But after a series of extra costs came to light and the attorney general of Connecticut launched a scathing attack on the siblings for promoting the card, the trio decided to end their endorsement deal in November 2010. Now they have been targeted in a $75 million lawsuit by bosses at the Revenue Resource Group, the company behind the scheme.

In papers filed at a court in Fresno, California earlier this month, the Kardashians are accused of wrecking the company's reputation by quitting their two-year deal, according to TMZ.com.
