The results of a toxicology reports are set to be announced on Thursday by Detective Chief Inspector Paul Fotheringham at an inquest hearing in Gravesend, Kent. Those reports will confirm that the 25-year-old died of a drugs overdose, according to the Times.
Peaches was found dead at the home she shared with husband Thomas Cohen and their two young sons on 7 April, in what was described by as a "non-suspicious" and "sudden unexplained" death. Her 11-month-old baby Phaedra was with her at the time.
Police found no evidence of drug paraphernalia in the house, leading to speculation that it may have been removed before their arrival.
The alarm was raised by musician Thomas, 23, who had spent the previous evening away from home with the couple's eldest child Astala, 23 months. He asked a friend to visit the property when he was unable to get hold of his wife.
Peaches' mother Paula Yates died from a heroin overdose in 2000. The TV star was found at her home in Notting Hill having taken an accidental overdose while she was alone with her daughter Tiger-Lily, then aged four.
Peaches herself had a long history of drug use, including reports she had to be revived after an overdose in 2008. Friends said she had stopped using drugs before the birth of her children.
According to the Times, there was speculation that she might have accidentally overdosed because her body could not tolerate the quantities of heroin she had previously taken.
Peaches' funeral took at Mary Magdalene & St Lawrence in Davington Kent — the same church where she was married, and where her mother's own funeral was held.
In her final interview, Peaches said that becoming a mother had helped her deal with the loss of her own parent.
"Now that I am a mum I can correct those awful parts of my childhood and it’s a really healing process," she said.
"Before, I was not at peace with myself about it because I was just traumatised. That's why I was living a chaotic lifestyle. But now I have the kids I can heal the situation. It's so good in every single way, really."
