On Wednesday (September 11), the BBC reported that the 18-year-old accidentally died from a fatal combination of cocaine and traces of Xanax and OxyContin.
According to the same BBC report, the teenager purchased cocaine the night before her death explaining, "In a statement, her GP Dr Paul Eulinger said the 18-year-old 'refused to give up drugs in the knowledge they could kill her… She was an individual who took drugs deliberately and has succumbed to their... effects accidentally.'"
The teen sadly passed away on March 13, 2019 after being found unresponsive by a friend.
The former One Direction singer, who is the eldest of his siblings, spoke out in April following his sister's death. While not directly mentioning his younger sister, the singer wrote an insightful message on how he plans to make the most of his life.
His younger sisters also honored Félicité through touching Instagram posts. "My precious sister. My heart is bleeding. I keep imagining and praying they have the wrong person. Not my sister, my best friend," 14-year-old Daisy wrote.
The death of Félicité comes two years after Tomlinson and his family lost their mother, Johannah Deakin, in 2016 to Leukemia. Tomlinson released the touching ballad "Two Of Us" just days before his sister's passing and has bravely performed it live a number of times.
Our thoughts are with Louis and his family.
