Kelly Osbourne says she became extremely thin after her father, rock musician Ozzy Osbourne, died and only realized how much she had changed when she saw a photograph from a dress fitting for the Grammys. She says she wore a wig at the awards to help conceal her cheekbones.

The outlet reports her comments as reflecting on a period of grief and how her appearance changed during that time. The description emphasizes that she did not notice the extent of the weight loss until reviewing images taken for a formal event. Aside from the weight-loss account and the reason she wore a wig, the report does not add further details about timing, quantities of weight lost, or medical context.

Because both sources provided are the same story from the same outlet, there is no separate confirmation or contrasting reporting from other organizations in the supplied text.
