At the time, it was reported that the budding fashion designer – known as Fizzy, to her friends - collapsed at her home after suffering a heart attack.
Felicite’s tragic death came just two years after her and brother Louis’ mother, Johannah Deakin, died of leukemia at age 43. It is understood that Felicite had a long history of drug use following her mother’s tragic death.
Coroner Dr Shirley Radcliffe said at today’s inquest: “It was a perfect storm, the oxycodone, the alpraxolam (Xanax) and cocaine.
“She was an individual who took drugs deliberately and has succumbed to their said effects accidentally.
“I find no evidence this was a deliberate act to end her life.”

During the inquest, Dr Paul Eulinger said in a statement: “She admitted she didn’t want to give up drugs and she knew it could kill her.”
The 18-year-old was diagnosed with ADHD, PTSD, borderline personality disorder, an eating disorder and poly-substance abuse while in rehab in Egypt.
An inquest into Felicite’s death revealed that her famous brother had begged her to get help – with the singer often accompanying her to doctor’s appointments.
Louis broke his social media silence one month after his sister’s death, thanking his fans for all their support.
