Singer/actress Jessica Simpson is facing a federal lawsuit, after a Los Angeles woman filed papers accusing the star of copying her trademarked cosmetics range.

MARA FOX launched Love Potion beauty products back in 1989 and now believes Simpson and business partners Sephora and D'Lish Fragrance infringed her copyright when they launched Dessert Beauty Deliciously Kissable Love Potion in 2004, reports PageSix.com

Simpson has used her image to market a range of cosmetic products. The THESE BOOTS (ARE MADE FOR WALKIN') singer also endorses acne treatment Proactiv.
