Kelly Osbourne is remembering her father, Ozzy Osbourne, with an emotional tribute that calls back to a special father-daughter moment.

Two days after Ozzy died at age 76, Kelly shared lyrics from the Black Sabbath song “Changes,” which she and Ozzy recorded as a duet together in 2003, to her Instagram Stories.

“I feel unhappy I am so sad,” Kelly, 40, wrote on Thursday, July 24. “I lost the best friend I ever had 💔”

“Changes,” which Ozzy co-wrote with his bandmates, was first released by Black Sabbath in 1972. In 2003, he and Kelly recorded a version as a duet with revised lyrics that reflected on their bond. The song was a No. 1 hit in the U.K., and they became just the second father-daughter pair to top the charts, after Frank and Nancy Sinatra in 1967.

Ozzy’s family announced his death with a statement signed by Kelly, her mother Sharon, her brothers Louis and Jack, and her sister Aimee.

“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.”

The English singer and songwriter, who was inducted into the Rock and Roll Hall of Fame twice — as a member of Black Sabbath and as a solo artist — was known for his rock star status, which earned him the nickname “The Prince of Darkness.”

But outside of his music career, he was just as well known for his love for family.

In 2002, Ozzy, Sharon, Kelly and Jack, now 39, became TV sensations with their Emmy-winning MTV reality series The Osbournes.

Their ups and downs, quirky moments and close bond played out on camera.

Ozzy had a total of six children: Jessica and Louis with ex Thelma Riley, as well as son Elliot, whom he adopted from a previous relationship. Ozzy and Sharon, who were married for more than 40 years, also shared daughters Aimee and Kelly, and son Jack.

 Ozzy revealed in 2020 that he was diagnosed with Parkinson’s disease, and while the progressive neurodegenerative disorder affected his mobility, he was still present for one of Kelly’s biggest moments, which came just weeks before his death.

Slipknot keyboardist Sid Wilson proposed to Kelly during Ozzy’s final concert with Black Sabbath at England’s Villa Park on July 5.

A video of the moment shared to Instagram showed Wilson, 48, backstage with his longtime love and her parents, telling her, “Kelly, you know I love you more than anything in the world,” before Ozzy jokingly interjected, “F— off, you’re not marrying my daughter.”

Kelly and Wilson welcomed their son Sidney in 2022.

She told PEOPLE in May 2024 that she lived with her parents during her pregnancy while Wilson toured with Slipknot.

“I did everything with him for a whole nine months,” she said. “It was more than nine months because I moved back in with my parents when I was pregnant because Sid was on tour and I didn’t want to be by myself.”

Kelly called the time with her family an “amazing experience,” adding, “I’d never give that back for anything.”

This past May, Kelly told PEOPLE her 2-year-old was “best friends” with his grandfather.

“Oh my God, they’re best friends,” she said of her toddler and her dad while at the 32nd Annual Race to Erase MS Gala. “So, favorite time of the day is nighttime because [Sidney] leaves me and gets in bed with my mom and dad because I’m staying in their house right now while my house is getting ready.”

“And he goes and gets in bed with them and they have cartoon time together and it is the sweetest thing ever …, ” she added.
