Kelly Osbourne is mourning the loss of her father and "best friend," Ozzy Osbourne, who died on Tuesday at age 76. This tragic event comes just weeks after Ozzy performed with Black Sabbath in his hometown of Birmingham, during what became his farewell show. The concert was especially emotional for Kelly, as she celebrated her engagement to Sid Wilson, her longtime partner from the band Slipknot, backstage.

Family members, including Sharon and Jack Osbourne, gathered at Villa Park to support Ozzy during his final performance, which featured contributions from famous rock musicians such as Ronnie Wood and members of Metallica and Guns N' Roses. As the band credited with birthing heavy metal, Black Sabbath holds a significant place in rock history.

Kelly shared her grief on Instagram, posting the lyrics to "Changes," a song she and her father recorded together, which topped the UK singles chart in 2003. The heartfelt lines she shared included, "I feel unhappy I am so sad. I lost the best friend I ever had," accompanied by a broken heart emoji. The close-knit Osbourne family, known for their strong bond, gained fame through their MTV reality show, The Osbournes, which aired from 2002 to 2005. More recently, the family resumed their podcast, discussing life and memories together.

The Osbourne family released an official statement expressing sorrow over Ozzy's passing, describing it as a loss that is hard to articulate, emphasizing he died surrounded by family and love. They did not disclose the specific cause of death, but Ozzy had been facing a number of health challenges, including a Parkinson's diagnosis in 2019. Tributes continue to pour in from fans and fellow musicians, reflecting on the indelible mark Ozzy has left on the world of music.
