After the death of her father, the 41‑year‑old television personality and singer has spoken candidly about the physical toll of grief, admitting a dramatic weight loss that surprised even herself. In a new interview with the Mail on Sunday, Kelly Osbourne explained that she had shed a significant amount of weight following Ozzy Osbourne’s passing in July 2025.

"I looked like the f‑‑‑ Crypt Keeper," she said, describing how thin she had become. She didn’t realize the extent of her transformation until she saw photographs of herself in a loose‑fitting dress on the red carpet at the 2026 Grammy Awards.

Ozzy Osbourne, the former Black Sabbath frontman, died on July 22, 2025, at the age of 76 after a heart attack. He had performed a final show in Birmingham on July 5, 2025, before his death. According to family reports, his body was kept at home for several days after the passing.

In the interview, Kelly attributed her physical changes to the intense pain she felt after her father’s death. "I was in so much pain that I didn’t see what other people saw. I just saw a broken person," she said. She added that she had worn a wig to conceal her face and "to hide how skinny my cheekbones really were," crediting her stylists for selecting an outfit that would not accentuate her slender frame.

Kelly attended the February 1, 2026, Grammy Awards in Los Angeles with her mother, Sharon Osbourne, and her brother, Jack Osbourne. The ceremony included a tribute to the late rocker, led by Post Malone who performed a rendition of Black Sabbath’s “War Pigs” alongside Slash and Chad Smith. Kelly said she was scared to attend but wanted to support her mother and honor her father’s legacy. "I didn’t think I should have gone. I wasn’t very well… You’re filled with so much pain that the feeling of hunger can’t even pop up," she recalled.

The Osbourne family has spoken publicly about the impact of Ozzy’s death on their lives. Kelly credited her three‑year‑old son, Sidney, with helping her rebuild after the loss. She said she tries to shield Sidney from seeing her distress, noting, "Whenever he walked in the room, something would come over me, and I’d snap into Miss Fun Mom. I didn’t cry in front of him. I always made sure that he was not exposed to inappropriate sorrow."

Kelly’s comments arrive amid a broader conversation about mental health and grief within the entertainment industry. While she has not disclosed any medical treatment for her weight loss, her statements highlight the physical toll that bereavement can take on individuals.

The 2026 Grammy Awards, held at Crypto.com Arena, also featured other performances honoring Ozzy Osbourne’s influence on rock music. The tribute was well received by audiences and fellow musicians, with Post Malone’s version of “War Pigs” described as a powerful homage.

As of September 6, 2026, Kelly Osbourne continues to work on her music and television projects. She has not announced any new releases, but her appearance at the Grammys and her candid discussion of her health suggest she is navigating a period of personal recovery. The Osbourne family remains active in preserving Ozzy’s legacy, with Sharon Osbourne continuing her role as manager and public figure.

The story illustrates how the death of a prominent public figure can affect the physical and emotional well‑being of close family members, and it underscores the importance of support systems during times of grief.
