Peaches Geldof, the late British socialite daughter of musician Bob Geldof, succumbed to a heroin overdose, according to reports.

Geldof died April 7 at age 25, leaving family and British authorities bewildered. She was found in her home in South London, where she had been caring for her  11-month old son. According to the Times of London, Geldof perished in a manner tragically similar to that of her mother, Paula Yates, who died of a heroin overdose in 2000 while caring for Peaches’ younger half-sister, Tiger Lily Hutchence Geldof.

An inquest is reportedly set for Thursday. An initial autopsy report had been inconclusive and determination of the cause of death was awaiting a toxicology report.

Hutchence Geldof has been dealt a particularly rough set of circumstances. Her father, INXS lead singer Michael Hutchence, was found dead in his hotel room when she was 16 months old. When she was four, her mother, Yates, died of a heroin overdose. After Yates’ death, Bob Geldof was given primary custody of Hutchence Geldof, whom he adopted, to keep her close to her sisters, Peaches, Pixie, and Fifi Trixibelle. Now she must cope with the death of her sister, who according to the Times, had grown more and more obsessed with their mother’s death.

In the wake of the tragedy, Bob Geldof is still trying to find some happiness. The Live Aid founder proposed to his girlfriend of 18 years, the French actress Jeanne Marine.

“She is over the moon,” Jerry Hall told the Daily Mail. “Jeanne Marine has been a rock and a tower of strength over this. I’m so excited for her I am bursting to tell someone. Bob and Jeanne have been through hell, but they are determined something positive will come out of it. After all the sadness, we need something to focus on which will bring joy and light.”

Hall, the former wife of Rolling Stones frontman Mick Jagger, was one of a few celebrities who attended Peaches’ funeral last week. Others included Kate Moss and Bill Wyman, the Stones’ bassist.

“It was, of course, terribly sad, but she told me that Bob had asked her to marry him out of the blue,” Hall said. “I’m so happy for her. It makes you realize we all have to value what we have.”
