Kelly Osbourne discusses health toll following Ozzy Osbourne's death

Kelly Osbourne has opened up about the severe physical and emotional toll taken by the death of her father, rock legend Ozzy Osbourne, in July 2025. In recent interviews, she revealed that she experienced drastic weight loss due to grief, noting that she did not realize the extent of her physical change until seeing a photograph during a dress fitting for the Grammy Awards.

Osbourne described her appearance at the time as scary, stating, “I looked like the f---ing Crypt Keeper,” and noting that her spine was clearly visible. To avoid drawing attention away from her father’s legacy during the Grammy tribute, she wore a wig to hide her sunken cheekbones and worked with stylists to find clothing that would mask her thinness. She admitted that she was not in a healthy enough state to attend the ceremony.

Beyond her physical health, Osbourne discussed her struggle with appetite and the difficulty of parenting her three-year-old son, Sidney, while navigating intense sorrow. She is now planning a three-part documentary series focused on grief and mental health to help others facing similar bereavement.

Separately, Jack Osbourne shared experiences of feeling his father’s presence through coincidental encounters, while Sharon and Jack Osbourne have been involved in the development of an Ozzy Osbourne-themed haunted house at Universal Studios.
