"American Idol" (search) winner Carrie Underwood (search) will sing classic jingles in a new television ad campaign for the Hershey Co.

Underwood, a native of Checotah, will sing "sometimes you feel like a nut ... sometimes you don't" for Almond Joy and Mounds.

She also will sing "give me a break" for Kit Kat and "Hershey's is ... the great American chocolate bar."

Having Underwood sing the jingles gives a modern twist to the candy, Jay Cooper, Hershey's vice president of U.S. chocolate brands, said recently.

Underwood, 22, also will be a spokeswoman for Skechers, a California sneaker maker, in an ad campaign.
