Ozzy Osbourne's Official Cause of Death at 76 Revealed

Details surrounding the rock icon’s death have now been formally released, offering insight into his last days.

A newly released document has confirmed the cause of death for Ozzy Osbourne, the pioneering heavy metal artist who died at age 76 on July 22, 2025. The news marks the end for one of rock's most influential figures.

According to the death certificate released by The Sun on August 5, the rock legend died of "acute myocardial infarction" and "out of hospital cardiac arrest." Coronary artery disease and Parkinson's disease were also listed as contributing factors in his death.

In the section called "Occupation and usual Address," Ozzy was referred to as "rock legend, songwriter and performer," as well as "husband of Sharon Rachel OSBOURNE Music Artist Manager [sic]."

The news of the icon's passing was announced on Instagram by his wife and his children, Jack, Kelly, Aimee, and Louis Osbourne.

This was only weeks after performing his farewell show "Back to the Beginning" with the original members of Black Sabbath at the Villa Park stadium in Birmingham. It was the first — now last — time they had played together in 20 years.

Following his death, Ozzy Osbourne was officially laid to rest on July 31 near the lake at his house in Buckinghamshire, after a massive memorial event in Birmingham the previous day.

His grieving family attended the service on July 30, with Sharon appearing especially emotional. As previously reported, she walked slowly while clinging to the arms of her children, Jack and Kelly. The TV personality was dressed in black, and her face was filled with grief as they all mourned together.

Photos from the service captured the rawness of that moment. Sharon was leaning on her children for support, her body heavy with sorrow. The pain of losing Ozzy, her husband of many years and partner through every twist and turn of life, was written all over her.

The family stood side by side in silence, united not only in mourning but in the deep love they shared for the man they were saying goodbye to.

At one point during the ceremony, Sharon raised her hand in the iconic rock-and-roll salute Ozzy made famous throughout his career. That single, heartfelt gesture was captured on video. It was a quiet but powerful tribute. It wasn't a grand moment, but it meant everything.

The images and video from the service quickly sparked an outpouring of emotion online. People across social media were struck by how fragile and devastated Sharon looked.

One person wrote, "She looks absolutely broken and so frail💔," while another added, "I hate seeing Sharon so fragile :'( R.I.P Ozzy Osbourne. Rest easy."

It wasn't just her visible grief that touched people; it was the small, intimate detail around her neck. "Oh poor Sharon. She looks so frail bless her heart. I see shes wearing Ozzys wedding band on her necklace [sic]😢 ❤️" someone noticed. That wedding band quickly became one of the most talked-about images from the service.

Fans on Reddit reflected on its significance. One wrote, "She looks so thin & broken. I really feel so sad for her. I know some people don't like her but she was everything to Ozzy for decades. They were together constantly. This has to be so incredible hard for her [sic]."

Another shared, "She has his wedding ring around her neck....I lost my dad unexpectedly last November, this hurts more than I would like [sic]." Someone else asked, "Is she wearing his wedding band around her neck?"

On Instagram, the grief was just as palpable. A fan commented, "I hope Sharon can hold on. So looks so pained and full of grief." Another wrote, "His ring around her neck 😢 I can feel their pain rip [sic]," while a third added, "She is wearing his wedding band around her neck. ❤️😢"

Surrounded by family and a grieving public, Sharon's expression in that moment said more than words ever could. There was appreciation for the fans who had shown up, for the music that brought them all together, and for the life she had shared with the man she now mourned.
