Félicité Tomlinson's tragic last hours were recounted in detail at an inquest into her death today.
The 18-year-old sister of One Direction singer Louis died after taking an accidental overdose of Alapraxolam, Oxicodone and cocaine at her west London apartment.
Félicité's horrified school friend Zainab Mohammed discovered her lifeless body in bed on March 13 after they had bought and taken cocaine the night before.
The inquest head that Félicité had spiralled into depression and drug abuse after losing her mother Johannah Deakin to cancer in December 2016.
Midwife Johannah died of leukaemia at the age of 43, leaving behind seven children - including Félicité who was just 16 at the time.
After the tragedy, Félicité suffered with PTSD and started to abuse drugs.
She was sent to rehab in Egypt last September, but after being allowed home for Christmas Félicité got back in touch with people who took drugs with her against medical advice.
The night before she died, Félicité and her school friend Zainab Mohammed had brought cocaine before a sleepover.
The inquest heard how Félicité 'had used different kinds of drugs' including cocaine, acid and MDMA.
The Coroner said: "You then say that both you and Fizz did lines of cocaine on the night of March 12th.
"A male friend came round, but he didn’t want any lines.
“You went to bed and saw Félicité do more lines, but you don’t know how many she did and then you fell asleep."
Ms Mohammed confirmed she wasn’t aware of any other drugs that were taken that night.
She had initially denied taking drugs but later admitted to police that she found her friend with her “lips whiteish” shortly after 12 noon and called a friend who told her to dial 999.
Paramedic Daniel Bollard was called to Félicité at 1.18pm and was told she had been found “lifeless” on her bed.
Medics found her not breathing with vomit in her airways and tried to revive her with CPR but she was pronounced dead at 1.45pm, having been in cardiac arrest for 54 minutes.
Police later declared the death “non-suspicious”.
A post mortem didn’t reveal any natural cause of death, but toxicologist Dr Susan Paterson said “toxic” levels of Oxicodone as well as cocaine and Alpraxolam, or Zanax, were found in her blood.
The coroner Dr Shirley Radcliffe asked: “It’s just a perfect storm, the Alapraxolam, Oxicodone and the cocaine?"
Dr Patterson, who gave a medical cause of death of ‘drug toxicity’, said: “Yes, that’s correct it’s the combination.
"Both of these drugs cause respiratory depression. So the effects add up. Also you’ve got cocaine which was present. It’s the combination of the three drugs which would have proved fatal.”
A tribute by her father Mark Tomlinson, a trade sales officer, was read out at Westminster Coroner's Court.
He said she ”was a much loved daughter and sister” and had from an early age “established herself as mischievous and wonderful with children.”
Mr Tomlinson added: “Felicite had huge hopes and aspirations for her future, a lot of which were beginning to come to fruition at her untimely passing.
“She is missed by all who knew and loved her.”
