The death certificate confirms the 76 year old rock legend died of cardiac arrest on 22 July in London

Ozzy Osbourne, the legendary Black Sabbath frontman and one of the most influential figures in heavy metal, died of cardiac arrest, according to his official death certificate.

The document, filed at a registry in London by his daughter Aimée Osbourne and obtained by The Sun and The New York Times, lists the official cause of death as “(a) Out of hospital cardiac arrest (b) Acute myocardial infarction (c) Coronary artery disease and Parkinson’s disease with autonomic dysfunction (Joint Causes).”

Osbourne died on 22 July at the age of 76. His death brought to an end a career spanning more than five decades, from his early days with Black Sabbath to a successful solo career and his later reinvention as a reality television personality.

In a statement released shortly after his death, the Osbourne family said: “It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning. He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time.”

His funeral was held on 30 July in his home city of Birmingham, England. Thousands of fans lined the streets as the hearse carrying the musician passed through the city centre, paying tribute to the man widely credited with helping shape the sound of modern heavy metal. His wife, Sharon, and children Aimée, Kelly, and Jack attended the private service, joining mourners for what was described as an emotional farewell.

Osbourne’s death came just weeks after what would become his final live performance. On 5 July, he reunited with his original Black Sabbath bandmates for the first time in nearly 20 years during a farewell concert, delivering a last bow to fans who had followed his career since the band’s formation in 1968.

In recent years, Osbourne had battled significant health problems. A fall in 2019 aggravated a previous spinal injury, leading to multiple surgeries. In 2020, he publicly revealed he had been diagnosed with a form of Parkinson’s disease the year before.

Speaking to Good Morning America in 2020, Osbourne described the toll of his diagnosis and recovery. “It’s been terribly challenging for us all,” he said. “I did my last show New Year’s Eve at The Forum. Then I had a bad fall. I had to have surgery on my neck, which screwed all my nerves.”

Known as the “Prince of Darkness,” Osbourne rose to fame in the early 1970s with Black Sabbath, whose pioneering sound defined the heavy metal genre. After leaving the band in 1979, he launched a hugely successful solo career, releasing landmark albums such as Blizzard of Ozz and Diary of a Madman. His influence extended beyond music into television, with The Osbournes reality show bringing him and his family into millions of homes in the early 2000s.

Despite his public persona as a hard-living rock star, Osbourne often spoke candidly about his struggles with health and addiction, earning him a reputation for resilience. His death marks the loss of one of rock’s most enduring and iconic figures
