Kelly Osbourne is in mourning after the death of her father, the legendary Ozzy Osbourne, who passed away at the age of 76. Described by Kelly as her "best friend," the iconic rocker died on Tuesday, leaving a profound void within the Osbourne family and the music community. Just weeks before his death, Ozzy performed with Black Sabbath in Birmingham, an emotional farewell concert attended by family and notable musicians like Ronnie Wood from the Rolling Stones and members of Metallica and Guns N' Roses.

In tribute to her father, Kelly shared bittersweet memories on social media, quoting lyrics from their collaborative song “Changes,” which reached number one on the UK singles charts in 2003. She accompanied the heartfelt message with a broken heart emoji, reflecting on their bond: “I feel unhappy I am so sad. I lost the best friend I ever had.” Their close relationship was well-documented on the MTV reality show "The Osbournes," which ran from 2002-2005 and showcased their family dynamics.

Following Ozzy's passing, the Osbourne family released a statement expressing their sorrow, emphasizing the love and support he had while surrounded by his family. They did not disclose a specific cause of death, although it was known that Ozzy had faced several health challenges, including a Parkinson's diagnosis in 2019. The tribute echoes the sentiments shared by fans and peers alike, who recognize the immense impact Ozzy Osbourne had on the world of music and culture.
