Félicité died on Wednesday after a suspected heart attack at her London apartment. Police responded to a call of a female in cardiac arrest and she was pronounced dead at the scene. She was 18.
Her younger sister Phoebe Tomlinson and Phoebe's twin Daisy Tomlinson both took to Instagram on Sunday where they mourned the loss and wrote about their sister's profound impact on the twins' lives. Phoebe shared a photo of a baby Félicité and said she and her family were all "shocked and heart broken."
Phoebe began, "You were my best friend, sister, motivator and person that could make me laugh until I cried. I'm lost without you and the thought of never seeing you again scares me like you wouldn't believe. I will love you forever and ever and you and mama will have a place in my heart until the day I die."
