Kelly Osbourne, the daughter Ozzy Osbourne, says she’s “not doing so great”, since the Black Sabbath frontman’s death.

The 41-year-old was speaking on the red carpet of the 2026 Grammy Awards, ahead of a tribute performance to her father in Los Angeles on Sunday (Monday AEDT).

The Black Sabbath singer died aged 76 in July last year, after being diagnosed with Parkinson’s disease in 2019.

On Sunday, his daughter was asked how she was coping since his death.

“To be honest with you, I won’t lie, people usually say I’m great, I’m not doing so great,” Osbourne said.

“It’s the hardest thing I’ve ever been through in my life, but I’m getting through, and we’re doing everything we can to try and just live in his legacy and be happy.”

The tribute performance featured rapper Post Malone, Andrew Watt, Red Hot Chilli Peppers drummer Chad Smith and Guns And Roses members Duff McKagan and Slash.

“It means more than I can express into words to see his peers in this community cherish him in such a way and a way that he deserves, and it’ll be very emotional,” Osbourne said.

“I’m here to support my mum, because it’s just as much about her as well, he wouldn’t have been him without her and vice versa.”

In the weeks before his death, Ozzy took to the stage as part of the Back To The Beginning concert, in which he reunited with his bandmates at Birmingham’s Villa Park.

Earlier at the Grammys, pop rocker Yungblud scooped best rock performance for his cover of Black Sabbath’s Changes at the band’s farewell concert.

A month ago, Osbourne publicly hit back at critics of how much weight she had lost since her father’s death.

” ‘What do you expect from me? What do you expect me to look like right now?’” she wrote in an Instagram story.

“The fact that I’m getting out of bed and facing my life and trying to be more than enough, I should be commended for that.

“For example, you say that I look ill. Well, I am ill right now. My life is completely flipped upside down.

“I don’t understand how people expect me to bounce back and look like everything is just fine in my life when it’s not.”

Osbourne said she’d received much “lovely, lovely, lovely” support since her father’s death but she was also shocked at the “disgusting, horrible, mean, rude” things that some people had said.

“It’s absolutely devastating that women can’t support other women,” she wrote.

“They’d rather tear them down when their dad just died. It’s disgusting, and I’ve had enough of it. So, go f— yourself.”

It came just after her mother told British broadcaster Piers Morgan that Kelly had struggled to eat since her dad’s death.
