The world of rock is in mourning. Ozzy Osbourne, the trailblazing frontman of Black Sabbath and a towering figure in the rise of British heavy metal, has died aged 76, his family confirmed on July 22. Known as the “Prince of Darkness,” Ozzy transformed music forever — but to his daughter Kelly Osbourne, he was simply Dadda.

As tributes flood in from fans and fellow artists across the globe, Kelly Osbourne shared a deeply personal message on Instagram, honoring the man behind the legend. Alongside a heart-melting throwback photo of a young Kelly sitting in Ozzy’s lap, she wrote:

“You gave the world your fire, your music, your madness. But to me, you gave the warmth of your arms, the laughter that lit up rooms, and a love only a daughter could understand. Happy birthday in heaven, Dadda. You’ll live forever in me.”

The photo — showing a smiling, long-haired Ozzy cradling his little girl — stands in stark contrast to his famously dark on-stage persona. It’s a reminder that behind the growling vocals and wild performances was a devoted family man, a soft-hearted father who treasured time with his children.

Ozzy, who rose to fame in the 1970s as Black Sabbath’s frontman before launching a massively successful solo career, spent his final days surrounded by his family. His wife Sharon, children Kelly, Jack, Aimee, and his grandchildren were reportedly at his side until the end.

“He was larger than life,” Jack Osbourne said, “but at home, he was just Dad — kind, funny, and always singing to the grandkids.”

Kelly’s tribute has touched hearts across social media, with fans echoing her sentiment: Ozzy may be gone, but his spirit — and his music — are eternal.

From bat-biting lore to stadium anthems, from chaos to comfort — Ozzy Osbourne redefined what it meant to be a rock star. And in the quiet moments, like the one Kelly shared, we’re reminded that his greatest legacy may not be the records he sold, but the love he gave.
