Chiefs at Herbalife International filed papers against Rick and Kathy Hilton on Tuesday, claiming that they were being paid royalties “erroneously” after originally backing the company in the 1990s, reports The Daily Express.
According to the documents, in 1992, the Hiltons provided services to Herbalife in a bid to launch a line of weightloss products.
The items were discontinued in 2002 after it was discovered they contained the drug ephedrine, which was banned by the Food and Drug Administration (FDA).
But, the Hiltons have allegedly been receiving royalties since then.
