Johnny Depp is paying a heartfelt tribute to one of his most revered rock legends.

The acclaimed actor surprised concert-goers by unexpectedly joining Alice Cooper during a thrilling performance at Cooper’s July 25 show held at London’s O2 Arena. This special appearance was dedicated to Ozzy Osbourne, coming just three days after the Black Sabbath icon’s family announced his passing at the age of 76.

In a captivating video shared on YouTube, the Pirates of the Caribbean star joined Cooper and his talented band mid-performance, contributing his musical skills as they delivered an electrifying rendition of Black Sabbath’s classic “Paranoid.” Depp showcased his impressive bass guitar proficiency, much to the delight of the enthusiastic fans who responded with raucous cheers and applause.

“Here’s to Ozzy!” Cooper shouted to the crowd, proudly wearing a T-shirt emblazoned with Osbourne’s likeness during the heartfelt performance.

Earlier that day, Cooper took a moment to reflect on his cherished memories of the legendary The Osbournes star, who bravely faced the challenges of Parkinson’s disease in the years leading up to his death. He reminisced about the decades of camaraderie shared within the vibrant heavy metal community.

“As I was making my way to the stage, I heard the news about [his death],” Cooper recounted in an interview with Planet Rock on July 25. “I couldn’t believe it; it just didn’t seem real. He had just performed, and I recall him signing autographs with such enthusiasm. But when the reality set in, it felt like a gut punch, even though deep down, you know it’s a possibility. It was truly shocking to the system.”
