"Nancy Sandra Sinatra" (born June 8, 1940, in Jersey City, New Jersey) is an American singer and actress. She is the daughter of the legendary singer Frank Sinatra and his first wife, Nancy Barbato.
For her fourth birthday, Phil Silvers and Jimmy Van Heusen wrote the song "Nancy with the Laughing Face," which her father recorded.
She began her career as a singer and actress in the early 1960s, initially with little success. In 1960, she married "teen idol" Tommy Sands but divorced him in 1965.
Her career peaked in the late 1960s with a string of pop music hits. Her best-known hit, "These Boots Are Made for Walkin'" — which popularized and made her synonymous with Go-go boots — was written by Lee Hazlewood and included session drummer Hal Blaine and guitarist Billy Strange on the recording — as did most of her other hits. "These Boots Are Made for Walkin'" and the music video featuring shapely, young women in tight sweaters, go-go boots and mini-skirts is considered a classic example of high camp. She currently is under the label Attack Records.
