Kelly Osbourne publicly pushed back against Dee Snider on Aug. 13 after the Twisted Sister singer questioned Ozzy Osbourne ’s songwriting contributions to Black Sabbath and his solo catalog. Snider’s comments followed fan discussions about the late metal icon’s collaborators, including Lemmy and Bob Daisley. The dispute began on social media after fans cited Lemmy’s co-writing credits on Ozzy’s 1991 album No More Tears . Snider claimed Sharon Osbourne, Ozzy’s wife and longtime manager, was unwilling to share credit, then alleged that Daisley wrote lyrics for Ozzy’s first two solo albums. Kelly Osbourne Was Not Letting That Slide Snider also said Geezer Butler wrote all of Black Sabbath’s lyrics and that Lemmy contributed lyrics to Ozzy’s music. He later argued that singers can make songs their own even when they do not write them, a defense that did little to cool the comment-section inferno. “My father’s legacy as a musician, songwriter, singer and bandleader speaks for itself,” Kelly Osbourne wrote. Kelly Osbourne’s first Instagram Story did not name Snider, but her follow-up post directly tagged him and mocked the age of his last hit, saying it arrived more than 40 years ago, around the year she was born. Her broader point was clear: Ozzy’s records, collaborators, fans and decades-long influence remain the receipts, while Snider’s songwriting claims are allegations rather than established fact.
