Nancy Sinatra Jr. announced the news of her mother's passing on Twitter, writing: "My mother passed away peacefully tonight at the age of 101".

"Godspeed, Momma and thank you for everything you did for us and for the world".

Nancy Sinatra Senior was born Nancy Barbato in 1917 and met Frank in 1934 at the New Jersey holiday resort of Long Branch.

Attempts to reach representatives for Nancy Sinatra Jr. late Friday were unsuccessful.

It was there that Nancy (best known for her hit song, "These Boots Are Made For Walkin") and Frank Jr. were born.

Nancy Sinatra Sr. married Frank Sinatra Sr., then an aspiring lounge singer, in 1939.

Frank Sinatra left his Nancy for Ava Gardner in the early 1950s. Nancy Sinatra worked as a secretary while her husband tried to get his music career started as a singing waiter at a local restaurant.

Nancy Sinatra, the first wife of singer Frank Sinatra and the mother of his three children, died this past Friday at the age of 101, as confirmed by her daughter, singer Nancy Sinatra.

According to CNN, her death also notably comes out around two decades after her husband's, who died of a heart attack in 1998 at the age of 82.

Daughter Tina later commented on their relationship, writing in her book My Father's Daughter: A Memoir: "It would take him two years to ask Mom for a divorce, and they were two of the roughest, most insecure years of Dad's life".

The Sinatras separated in 1950 and their divorce was finalised in 1951.

She also remained friendly with her ex-husband, who is said to have put in requests over the years for pasta and other Italian food dishes she was known to be an expert at preparing.

Gay Talese, in 1966, wrote there was "no bitterness", and instead, only "great respect and affection" between Frank and Nancy.
