Barbara Sinatra, the philanthropist and widow of singer Frank Sinatra, has died at the age of 90 after months of declining health, a spokesperson confirmed.
The American model and showgirl married the famous singer in 1976 and the couple were together for 22 years. It was the longest of Mr Sinatra’s four marriages.
She passed away at home in Rancho Mirage, California, surrounded by family and friends, he said.
The former model and Las Vegas showgirl was a committed, high-profile advocate for abused children, establishing the Barbara Sinatra Children’s Centre in California in 1986.
The centre, which provides counselling for victims of physical, sexual and emotional abuse, is funded by the Frank Sinatra Celebrity Invitational Golf Tournament. Mr Sinatra performed during the tournament until his last ever show in 1995. He died three years later.
Mrs Sinatra wed Frank in 1976. She had been married twice before – including to Zeppo Marx, youngest of the Marx Brothers comedy team – while he had three previous wives.
In her book Lady Blue Eyes: My Life With Frank Sinatra, Ms Sinatra wrote of her relationship with her late husband: “I was his companion, consultant, muse, psychiatrist and lover.”
Ms Sinatra is survived by her only child, Robert Marx, and one granddaughter.
