?Herbalife International just filed a lawsuit against Rick and Kathy Hilton, claiming the couple has been "erroneously" receiving royalties for several weight loss products for roughly 8 years.
Long story short -- Herbalife says in 1992, the couple provided services to the company to get a line of products off the ground ... products containing ephedrine that were discontinued in 2002 -- mostly because ephedrine was banned by the FDA.?
