Kelly Osbourne and Twisted Sister frontman Dee Snider are going head-to-head after the retired musician claimed Ozzy Osbourne "always" had other people write his songs for him.
Earlier this week, Snider wrote on X, "Ozzy always had bass players write his lyrics." He went on to claim that bassist Bob Daisley and Motörhead frontman Lemmy Kilmister were frequent writers of Ozzy's music, and that Geezer Butler "wrote ALL of @BlackSabbath lyrics."
According to Daisley's website, he claimed to have written the majority of the songs for Ozzy's first five solo albums. Daisley is credited as a songwriter on "Blizzard of Ozz" and "No Rest for the Wicked." During Ozzy's time with Black Sabbath, Butler was widely credited as the main lyricist for the band.
Snider's comments prompted a sharp response from Ozzy's daughter via her Instagram Stories Friday.

Kelly shared two text-heavy posts, including one directly addressing Snider.
"My father’s legacy as a musician, songwriter, singer and bandleader speaks for itself. His friends, those who worked with him, those who love him, and millions of fans around the world that still continue to buy his records know exactly what he meant what he contributed and what he leaves behind. His legacy will live on eternally," Kelly wrote on the first image.

In her next Instagram story, Kelly called Snider’s criticism "spectacularly classless" and argued that he had little basis to speak authoritatively about her father's career and legacy.
"And if Snider wants to invite comparisons between their careers, that comparison is devastating enough on its own," she wrote.
Kelly then compared Snider and Ozzy's careers, writing, "Snider had a brief period of mainstream success more than 40 years ago. My father's career spanned nearly six decades — from helping define heavy metal with Black Sabbath to building an extraordinary solo career. His music will continue influencing generations long after all of us are gone."

Kelly suggested that Snider’s criticism was an attempt to put himself back into the conversation, while her father’s "name, catalogue and influence" remain globally relevant. She argued that Ozzy’s accomplishments stand on their own, writing, "My father doesn’t need Dee Snider’s approval to establish his place in music history."
She concluded, "trying to make my father smaller won’t make Dee Snider bigger," arguing that attacking Ozzy’s legacy only draws greater attention to the difference between the two musicians’ careers and lasting cultural impact.
Early Friday morning, Snider returned to X to make it clear that he has "nothing but love for Ozzy."

"He was always lovely to me. @BlackSabbath changed my life! As a songwriter I can be a little touchy about credit and royalties," Snider wrote.
Representatives for Kelly did not respond to Fox News Digital. Snider's representative said the rocker had no further comment.
Ozzy died on July 22, 2025, at 76, just weeks after performing his final concert with Black Sabbath. His death certificate later listed cardiac arrest and coronary artery disease among the causes of his death, with Parkinson’s disease noted as a contributing condition.
