Guess there is such a thing as having too many endorsements. Teri Hatcher was tapped by the Hydroderm company for an "exclusive endorsement deal" in 2005, according to papers filed yesterday in Los Angeles Superior Court. Hydroderm claims Teri then went on to promote a competing brand, City Cosmetics. "Hatcher's name, image and likeness have been linked to so many competitors' products (at least 17!) that it is anyone's guess as to what product keeps her skin and lips youthful," says the suit. The company is suing for a complete refund of her $2.4 million endorsement deal, plus $400,000 in expenses. Teri's legal rep fired back that the allegations are an "unjustified and public assault on Teri Hatcher's good name, reputation and celebrity."
