Sir Tom Jones's wife of 59 years, Lady Melinda Rose Woodward, has died after a "short but fierce" battle with cancer.
She died on Sunday, surrounded by her husband and loved ones, a statement said.
The statement from Live Nation continued: "Sir Tom and his family have asked for privacy at this difficult time and no further information is currently available."
Known as Linda, she died at the Cedars-Sinai hospital in Los Angeles.
Sir Tom, 75, recently cancelled a number of his tour dates in Japan, Thailand, South Korea and the United Arab Emirates.
