Peaches Geldof died because of a heroin overdose just like her mother Paula Yates, according to reports.
The claims come just before inquest into Peaches' death opens on Thursday, the Mirror reported.
Peaches was found dead while caring for her 11-month-old son Phaedra on her own at the family home on April 7.
Her funeral was held at the same church as her mother's with celebs, including Kate Moss, Jools Holland and Bill Wyman among the mourners.
