Ozzy Osbourne built a career on outrageous performances and a larger-than-life public image, but behind the legendary status were relationships with fellow musicians that were far from harmonious. Over the decades, the Prince of Darkness found himself at the center of feuds with some of rock’s biggest names. While some rivalries were fueled by personal rejection, others grew from creative differences, business disputes, or public insults. Here is a look at six of the most surprising conflicts from his career.
One of the most unexpected encounters involved Frank Zappa. When Black Sabbath and Zappa crossed paths in Chicago in 1974, Ozzy suspected the famously eccentric musician was mocking the band. He even recalled preparing for a physical confrontation when Zappa invited Sabbath to his hotel suite. The reality was the opposite.
Zappa was a genuine admirer of the band, having praised songs like “Supernaut” and “Iron Man” as works of art. The meeting turned friendly, and Zappa even invited Sabbath to his birthday celebration. Later, at a Madison Square Garden show, Zappa introduced the band and watched from the sidelines. There was reportedly even a plan for Zappa to join Sabbath on stage, but technical difficulties during the performance led Tony Iommi to call it off.
Ozzy later admitted he had misunderstood Zappa’s intentions completely, and the two enjoyed a strange but respectful relationship for years afterward. Ozzy also had a long-standing grudge against guitarist Gary Moore. When Osbourne launched his solo career in 1979, Moore was his first choice for a guitarist. Moore, however, had no interest in joining the project and repeatedly turned him down.
Sharon Osbourne, who managed both musicians at the time, kept Moore involved in auditions, but he never committed to the band. Ozzy reportedly took the rejection personally, and the two developed genuine animosity. Moore later recalled Ozzy insulting his appearance, including a remark that Moore had a face like a welder’s bench. After Randy Rhoads died in 1982, Sharon approached Moore again, but he bluntly refused.
Moore acknowledged that Ozzy disliked him and had no desire to hide his own feelings. Yet Moore’s influence lingered—Rhoads had admired Moore’s playing, particularly the melodic work on “Parisian Walkways,” which Moore said echoed in Rhoads’ performance on “Mr. Crowley. ”
A more complicated and painful rift developed with Geezer Butler, Ozzy’s longtime bandmate.
The two had been together since Black Sabbath’s formation in Birmingham in the late 1960s. After Ozzy was fired in 1979, their professional paths crossed again, but Butler felt his creative contributions to Black Sabbath were often overlooked. In one incident, Butler sent musical ideas to Ozzy for a potential collaboration, but Ozzy didn’t listen because Butler wasn’t the guitarist. Their personal lives also created distance.
A serious falling out between Sharon Osbourne and Butler’s wife, Gloria, reportedly led to another extended period where the two musicians stopped speaking. In 2024, Ozzy publicly criticized Butler for not contacting him during a health crisis, prompting Butler to respond publicly with his side of the story. Their decades of shared history made every new conflict heavier, but it also made their bond impossible to fully sever. In 2005, Ozzy found himself in a very public feud with Bruce Dickinson of Iron Maiden.
The conflict exploded during Ozzfest, when Dickinson repeatedly made comments from the stage that the Osbourne camp saw as direct attacks. Dickinson openly criticized reality television, a clear reference to “The Osbournes,” and reportedly questioned Ozzy’s use of an auto-cue during live performances. Sharon Osbourne interpreted Dickinson’s remarks as ongoing disrespect. Tensions reached a breaking point at the August 20, 2005 show in San Bernardino, California.
Iron Maiden was pelted with eggs and other objects, and their sound was repeatedly cut off during the performance. When the set ended, Sharon took the stage and publicly confronted Dickinson, who responded that the festival was deliberately interfering with the show. The incident drew condemnation from Iron Maiden’s manager and became one of the most talked-about moments in Ozzfest history. Dickinson later maintained that his criticism was aimed at reality television culture, not Ozzy personally, and he described the feud as a “storm in a teacup.
” Ozzy, meanwhile, said he had not even been fully aware of what Dickinson was saying during the tour. Although both men eventually softened their positions, the confrontation remained a defining memory of that tour. The most painful rift came with Bill Ward, Black Sabbath’s original drummer. Ward and Ozzy shared a history stretching back to the late 1960s, but their relationship was marked by repeated disagreements over money, management, and substance abuse.
Ward later became openly frustrated with how the original band members were treated financially, believing the four founding musicians should have had greater control over their own affairs. The relationship suffered a major rupture in 2012 when Black Sabbath announced its final reunion without Ward. Ward said he was unwilling to sign what he considered an unacceptable contract, and he also disagreed with the way the situation was handled. Ozzy publicly claimed Ward was not physically capable of performing, a statement Ward strongly denied.
For Ward, the issue was about respect and contractual treatment, not his ability to play. Ward had performed on the band’s first six studio albums and had helped define its signature sound on songs like “War Pigs” and “Paranoid. ” Yet when Black Sabbath played its final show in Birmingham in 2017, Ward was not behind the drum kit. The absence carried enormous weight for a musician who had helped create the band from the very beginning.
Another chapter of tension came from Ronnie James Dio, who replaced Ozzy in Black Sabbath after the singer was fired in 1979. Dio’s arrival produced “Heaven and Hell,” an album that revived the band’s fortunes and gave it a new identity. Ozzy, who was building his own solo career at the time, had to watch his former band thrive with a different frontman. The rivalry became part of heavy metal culture in the early 1980s, with both singers commanding fiercely loyal audiences.
Years later, Dio criticized the Rock and Roll Hall of Fame for inducting only the Ozzy-era lineup in 2006, arguing that his era had also produced important music. When Iommi and Dio reunited under the name Heaven and Hell, the choice of name was itself a reflection of the ongoing tension with Ozzy. That reunion produced another successful album, “The Devil You Know,” in 2009, keeping the comparisons between the two singers alive. Dio’s death in 2010 ended any possibility of another confrontation between them.
But the rivalry left a lasting mark on Ozzy’s story. Dio did not simply replace Ozzy—he created a version of Black Sabbath that stood beside Ozzy’s legacy, and neither man’s history could erase the other’s.
