Kelly Osbourne Reacts To Father Ozzy’s Death With Black Sabbath Lyrics: “Best Friend I Ever Had”

Ozzy Osbourne‘s family is mourning the late rock legend following his death at age 76 on Tuesday.

On Thursday, the Black Sabbath frontman’s daughter Kelly Osbourne expressed her grief with a reference to the British heavy metal band’s 1972 ballad ‘Changes’ on her Instagram Story.

“I feel unhappy,” wrote Kelly with a broken heart emoji. “I am so sad. I lost the best friend I ever had.”

Kelly previously performed the song as a duet with her father in 2003, appearing as a single on her debut studio album Shut Up.

The Osbournes alum’s post comes after the family announced Ozzy’s death in a statement on Tuesday. Although he endured numerous health problems in recent years, a cause of death was not immediately disclosed.

“It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning,” the statement read. “He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time.”

In 2002, Ozzy and wife Sharon made their family debut on the MTV reality series The Osbournesfeaturing Kelly and son Jack. The show won the Emmy for Outstanding Non-Fiction Program (Reality) in 2002 and was nominated again the following year. Its final episode aired on March 21, 2005, before launching several offshoots over the years.
