Ozzy Osbourne's cause of death has been revealed.
The legendary Black Sabbath singer passed away on July 22 aged 76, and was laid to rest on July 31 following a funeral procession in his hometown of Birmingham, which was attended by his family.
And though the "War Pigs" singer had various health struggles in the last years of his life, including a Parkinson's disease diagnosis, his cause of death has now been ruled as a heart attack.

The certificate says Osbourne died of "(a) Out of hospital cardiac arrest (b) Acute myocardial infarction (c) Coronary artery disease and Parkinson’s disease with autonomic dysfunction (Joint Causes)."
Multiple outlets had previously reported that on the day of Osbourne's passing, an air ambulance flew to his home near the village of Chalfont St. Giles in Buckinghamshire, England.

After the stop in Osbourne's home, the ambulance flew about eight miles southwest to Harefield Hospital, in Uxbridge, a London suburb, according to Flightradar24, a company that collates data on aircraft movements. A Flightradar24 spokesman told the Times that the helicopter spent "about an hour" at the hospital with its engines running.

His death came on the heels of his farewell performance with the original Black Sabbath lineup, the first weekend of July, the first time they reunited in 20 years.
"It's so good to be on this [expletive] stage, you have no idea," he told the crowd of 42,000, per Variety, at the time, adding: "Let the madness begin!"
His wife Sharon, speaking with The Sun earlier this year about Osbourne's health, had said of his highly-anticipated return to the stage: "He's very happy to be coming back and very emotional about this," however added: "Parkinson's is a progressive disease. It's not something you can stabilize. It affects different parts of the body and it's affected his legs … But his voice is as good as it's ever been."
