Peaches Geldof was looking a little on the thin side when she showed up to a fashion event just days before she died.

Geldof was seen at the Somerset House in London for a fashion show on April 3, just four days before her death. Her weight was a constant source of concern by friends and family, and she looked a little thin at the event.

The 25-year-old was found dead at her home in Kent on Monday afternoon. Details surrounding her death are unclear, but investigators are treating the death as "unexplained and sudden."
