Barbara Sinatra, the wife of the legendary Frank Sinatra died on Tuesday aged 90.
She died surrounded by her family and friends in California of natural causes.
The former model and Las Vegas showgirl married Frank Sinatra in 1976 and was the last of his four wives. They were married for 22 years until he passed away from a heart attack in 1998.
In her 2011 book, "Lady Blue Eyes: My Life with Frank," she wrote of first meeting her future husband when she was asked to be a doubles partner with his second wife, Ava Gardner.
She spent time at Sinatra's Palm Springs home while she was married to his neighbour, Zeppo Marx, of the famous Marx Brothers family.
In 1986 she and her husband founded the Barbara Sinatra Children's Center, which is located on the Eisenhower Medical Center campus in California.
The center provides services for abused, neglected and at risk children.
Sinatra remained actively involved in the facility.
In March the Children's Hospital Los Angeles partnered with the center to raise $250,000 for services for children and their families being treated at both facilities, according to KESQ.
