Jessica Simpson says she works out and takes good care of herself. But that doesn't mean the girl doesn't like a cold beer once in a while. Makes sense, then, that the singer, actress, and designer has signed on as spokeswoman for a new beer that apparently contains not only alcohol, but vitamins.

Stampede Light Plus, made by the Dallas's Stampede Brewing Co., is the product Simpson will endorse. Why exactly this beer? Because she is always interested in diversifying her portfolio, she says. And she likes good ideas and good people. Oh, and a little money too -- Simpson will take a 15-percent stake in the brewer.
