Peaches Geldof reportedly died of a heroin overdose.
The 25-year-old socialite's body was found at the home she shared with husband Thomas Cohen and sons Phaedra, one, and Astala, two, in Wrotham, Kent, England, on April 7, and detectives will officially announce her cause of death at an inquest later on Thursday.
North West Kent Coroner Roger Hatch will confirm the results of a toxicology test, which found Peaches' died as a direct result of the class-A drug, and the inquest at Gravesend Old Town Hall will be immediately adjourned, according to the UK's The Times newspaper.
The news is sure to have come as a blow to Peaches' father, Sir Bob Geldof, as her mother Paula Yates, 41, also died of an accidental heroin overdose in 2000, when Peaches' was just 11.
Police discovered no evidence of drugs paraphernalia in the house, sparking speculation that a friend or family member may have removed evidence from the property prior to the arrival of paramedics.
An autopsy carried out on the blonde beauty's body by a Home Office Pathologist shortly after her death proved inconclusive, so samples of her blood and tissue were sent off to a laboratory for further testing.
A spokesman for the police station in Kent declined to comment on reports she overdosed and added: “The inquest opens later today and that is all I can say.”
The hearing is expected to last approximately 10 minutes and a full inquest into the model and TV presenter's death will take place in late July.
Peaches - who had reportedly become increasingly obsessed with her mother's death - was laid to rest last week at St Mary Magdalene and St Lawrence Church in Davington, Kent, where her father delivered a heart-breaking eulogy.
TV presenter Alexa Chung, model Kate Moss, Razorlight frontman Johnny Borrell, singer Eliza Doolittle, actress Jaime Winstone and Rolling Stones bassist Bill Wyman were among the other mourners at her funeral. - Bang Showbiz
