Kelly Osbourne has spoken publicly about the intense grief and physical toll she experienced following the death of her father, rockstar Ozzy Osbourne, in July 2025. The television personality revealed that her significant weight loss during this period was so pronounced that she felt compelled to wear a wig at the Grammy Awards earlier this year in an effort to conceal her gaunt appearance.

Osbourne, 41, said she was initially unaware of how thin she had become until she saw a photograph taken during a dress fitting for the awards ceremony. Describing her reflection with stark honesty, she said her visible spine and prominent bones alarmed her. Friends and family had expressed concern about her fragile state, but she explained that the depth of her grief left her unable to perceive her own physical decline. "I couldn’t see what other people saw because I was in so much pain," she said, adding that she saw herself as a "broken person."

Determined not to let her appearance overshadow the tribute to her father’s legacy at the Grammys, Osbourne employed a wig and stylists searched for clothing that would minimize the focus on her weight loss. She admitted that despite her efforts to be present for her family, she did not feel well enough to attend the event fully. The loss had a profound impact on her appetite, with grief inducing nausea that prevented her from eating properly.

In addition to coping with her own sorrow, Osbourne focused on protecting her three-year-old son, Sidney, from witnessing her pain. She described shifting quickly to a more upbeat demeanor whenever he entered the room and making sure he was not exposed to "inappropriate sorrow." She also reminisced about the close bond between Ozzy and his grandson, noting that Sidney has inherited many of his grandfather’s mannerisms and often visits Ozzy’s gravesite, where he leaves small tokens and talks about his day.

Ozzy Osbourne passed away at his home in Buckinghamshire aged 76, less than three weeks after performing his final concert in Birmingham, the city where he was born. His funeral procession drew tens of thousands of fans, with his family laying flowers at Black Sabbath Bridge, named after his iconic band.

Looking ahead, Kelly Osbourne plans to create a three-part television documentary exploring grief and mental health, drawing on her own experiences. While she has not yet disclosed the broadcaster involved, she aims to share an honest account of her journey through bereavement. Reflecting on the prolonged period of "anticipatory grief" as her father’s health declined over the years, she acknowledged that she had mistakenly believed she was prepared for his passing. "The person I was before my dad died is dead," she said, underscoring the profound change she has undergone.
