Whilst the London Ambulance Service added: "We were called at 12.51pm. We sent two ambulance crews, a single responder in a car and an advanced paramedic to the scene. Sadly, despite efforts of our medics, a person died."
As of the time of writing, Félicité's death is being treated as "unexplained", and a full post-mortem examination and toxicology tests are underway to determine the teenager's cause of death.
For 27-year-old Louis, the tragic news comes after he previously lost his mother Johannah Deakin in 2016, when she passed away aged 43 after losing her battle with leukaemia.
And Louis recently released a heartbreaking new single entitled 'Two of Us', in which he painfully sings about wishing he was the one who died.
On the track, he sings: "You'll never know how much I miss you, the day that they took you, I wish it was me instead."
And during the chorus, he adds: "I will be the best of me, always keep you next to me, I'll be living one life for the two of us."
