Kelly Osbourne says she has lost her "best friend" following the death of her father Ozzy Osbourne. The heavy metal pioneer died on Tuesday at the age of 76. He died just a few weeks after performing with Black Sabbath at a big farewell show in his hometown of Birmingham. The concert was particularly poignant for his daughter Kelly, who got engaged backstage to her long-time partner Sid Wilson, from the band Slipknot. Many family members were at Villa Park to support the so-called Prince of Darkness for what turned out to be his final performance. Famous musicians such as Ronnie Wood from the Rolling Stones, Metallica, and Guns N' Roses also took to the stage. His band Black Sabbath is credited with inventing heavy metal.

In 2003, the father-daughter duo released a cover of the Black Sabbath song "Changes," which reached number one on the UK singles chart. In her first comments since his death, Kelly Osbourne posted the opening lyrics from the song on Instagram along with a broken heart emoji: "I feel unhappy I am so sad. I lost the best friend I ever had." The father-daughter duo were known for having a close relationship and appeared together on the MTV reality TV show "The Osbournes," which ran from 2002 to 2005, showcasing their lives in an often humorous light. More recently, they reprised their family podcast alongside Kelly’s mother Sharon and brother Jack.

Celebrities and fans alike have been paying tribute to the legendary rock figure, who has left an indelible mark on the music industry.
