Dee Snider has said sorry to Kelly Osbourne for comments made about her late father Ozzy’s songwriting credits, which she labeled “spectacularly classless”.

The Twisted Sister frontman, 71, shared a series of posts last week that took aim at the Black Sabbath frontman.

Ozzy’s youngest daughter soon hit back, saying Snider’s remarks were an attempt to “belittle” her father, who died aged 76 in July last year.

Snider has now issued an apology on X.

Tagging Osbourne, he wrote: “Kelly Osbourne, I’m sorry what I said hurt you. It was never my intent. My sympathies on the loss of your dad.”

She has not yet responded.

After initially posting about Ozzy Osbourne, Snider went on to state he had “nothing but love for Ozzy” and that the singer was “always lovely to me” and his heavy metal band “changed my life”.

In a response set to her father’s track No More, Kelly Osbourne, 41, wrote: “My father’s legacy as a musician, songwriter, singer and bandleader speaks for itself.

“His friends, 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.”

In a later post, she added: “There’s something spectacularly classless about Dee Snider trying to diminish my father Ozzy Osbourne and his extraordinary abilities and achievements when he is no longer here to challenge his allegations.”

Snider’s comments were sparked by a conversation on X about song-writing credits and royalties, in which he referenced musicians including Lemmy and Bob Daisley, the latter of whom had a long-running dispute with Ozzy Osbourne on the matter.

Kelly Osbourne went on to highlight her father’s “nearly six-decade career”, adding he “helped define heavy metal and built an extraordinary solo career”.

She said: “His music will continue influencing generations long after all of us are gone. My father doesn’t need Dee Snider’s approval to establish his place in music history.”

She also called Snider “irrelevant” and “desperate”.

Ozzy Osbourne died just over two weeks after his Back To The Beginning farewell concert, where he was reunited with his bandmates.

This week, it was announced that the BBC documentary Sharon & Ozzy Osbourne: Coming Home, which followed the final three years of his life, had been nominated for a National Television Award in the authored documentary category. Kelly Osbourne has since posted about the nomination and urged people to vote ahead of the awards, to be held on September 8.

Posting on Instagram with a link to voting, she wrote: “Although I have never watched the documentary because it’s still so hard for me to see my daddy in his final days please vote. He truly deserves the recognition.”
