According to TMZ, the suit claims that Willis purchased the handmade $27,700 rug from Los Angeles shop Mansour and tried to return it after allegedly soiling it with red wine.
The store claims that it delivered the rug to Willis's home in "perfect" condition and even gave the Die Hard star a 10% discount.
Six weeks later, Willis, who had not yet paid for the rug, had it altered by ten inches and attempted to return it, despite that fact that it had been stained by "spilled or dripped red wine".
Mansour now wants Willis to play for the rug.
The star's lawyer Marty Singer called the suit "ridiculous", claiming that Willis never purchased the product and it was delivered on consignment.
