Kelly Osbourne has publicly clashed with Twisted Sister frontman Dee Snider after he made comments questioning the songwriting abilities of her late father, Ozzy Osbourne. The television personality, 41, took to her Instagram stories to defend her father's legacy after Snider suggested on X that Ozzy had others, such as bassist Bob Daisley and Motörhead frontman Lemmy Kilmister, write his songs.

"My father's legacy as a musician, songwriter, singer and bandleader speaks for itself," Kelly wrote in response. "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 further asserted that Snider's "last hit" was in 1984, the year she was born, and called him "irrelevant." She criticized what she described as "spectacularly classless" behavior from Snider for attempting to diminish her father's achievements after his passing. Kelly contrasted Snider's "brief period of mainstream success more than 40 years ago" with her father's career, which "spanned nearly six decades and helped define heavy metal."

She added that trying to diminish her father's status would not elevate Snider, but rather highlight the significant difference in their legacies. "It only reminds everyone of the enormous difference between their legacies and further proves how irrelevant Snider is to the music industry and society as a whole," she stated.

Snider later clarified his remarks on X, stating, "To be clear, I HAVE NOTHING BUT LOVE FOR OZZY. He was always lovely to me. Black Sabbath changed my life! As a songwriter I can be a little touchy about credit and royalties."

Ozzy Osbourne, the legendary heavy metal singer and frontman of Black Sabbath, died on July 22 at the age of 76. He performed his final concert, the "Back to the Beginning" show at Villa Park, just weeks prior. Osbourne, who sold over 100 million records, is remembered for his work with Black Sabbath, a band he formed in Birmingham in 1969, known for hits such as "Iron Man," "War Pigs," and "Paranoid."
