Nancy Sandra Sinatra (born June 8, 1940, in Jersey City, New Jersey) is an American singer and actress. She is the daughter of singer/actor Frank Sinatra from his first wife, Nancy Barbato, and remains known for her 1966 signature hit "These Boots Are Made for Walkin'".
For her fourth birthday, Phil Silvers and Jimmy Van Heusen wrote the song "Nancy (With the Laughing Face)", which her father recorded.
Her other popular recordings include "Sugar Town", "How Does That Grab You, Darlin'?" and the theme from a James Bond film, You Only Live Twice.
Nancy Sinatra began her career as a singer and actress in the early 1960s, but initially achieved success only in Europe and Japan. Then she had a transatlantic number-one pop with "These Boots Are Made for Walkin'", which showed her provocative but good-natured style, and which popularized and made her synonymous with go-go boots. The promo clip featured a big-haired Sinatra and six young women in tight tops, go-go boots and mini-skirts, and is considered[by whom?] a classic example of high camp. The song was written by Lee Hazlewood, who wrote and produced most of her hits and sang with her on several duets, including "Some Velvet Morning". In 1966 and 1967, Sinatra charted with 13 titles, all of which featured Billy Strange as arranger and conductor.
In 1967 she paired with her father for her second number-one single, "Somethin' Stupid". She also co-starred with Elvis Presley in the movie Speedway.
