"A female believed to be aged 18 was pronounced dead at the scene. A post-mortem examination will take place in due course."
Louis, 27, who was said to be very close to his younger sister, was informed of her death on Wednesday night.
He had been scheduled to perform his new single Two Of Us, which was written in honour of his late mother, on Comic Relief on Friday (March 15), but has now cancelled the appearance.
Louis and Félicité's mother Johannah died from leukaemia aged 42 in 2016.
