In a fiery response, Jack Osbourne has called out Pink Floyd's co-founder, Roger Waters, for his dismissive remarks about his late father, Ozzy Osbourne.

Waters, now 81, didn't hold back in a recent interview with The Independent, expressing his lack of respect for Black Sabbath and Ozzy's legacy following the legendary rocker's passing on July 22.

"I couldn’t give a f*** about Ozzy or Black Sabbath," Waters exclaimed. He further remarked, "The music? I have no idea," showing blatant disregard for the iconic band.

The comments struck a nerve as Waters continued to deride Ozzy's fame: "He was all over the TV for hundreds of years with his idiocy and nonsense," referring to the family's reality show, The Osbournes.

Taking to Instagram, Jack aimed straight for Waters’ jugular: "Hey @RogerWaters F*** You! How pathetic and out of touch you’ve become." He added, "My father always thought you were a c***—thanks for proving him right," trailing his statement with a clown emoji for emphasis.

This isn’t a singular incident; Jack’s sister, Kelly, 40, also recently confronted WWE star Becky Lynch after she made crass remarks about Birmingham—Ozzy’s hometown—during a live broadcast.

Following Ozzy's death, fans and family paid heartfelt tributes, with thousands of mourners lining the streets of Birmingham for his funeral procession. Sharon Osbourne and their children, Jack and Kelly, were notably present, honoring the legacy of the rock icon who had profoundly shaped the music world.

As Ozzy's family grapples with their loss, it’s clear they won’t shy away from defending his memory against criticisms, especially from figures like Waters, who seem to relish stirring controversy.
