One Direction star Louis Tomlinson's sister Félicité Tomlinson has tragically passed away from a suspected heart attack at her London home at just 18 years of age.
Reports suggest Louis has been left 'devastated and distraught' over the death of his sibling; with sources close to the social media star her as 'loveable, caring, bright and beautiful.'
The tragic news comes after Louis and Félicité's mother Johannah Deakin passed away from leukaemia in December 2016.
Félicité - known affectionately by fans as 'Fizzy' - is said to have collapsed after a suspected heart attack at her fourth-floor studio apartment in Earls Court, West London on the afternoon of Wednesday 13th March.
A friend who was with the social media influencer reportedly called 999; with two ambulances rushing to the address.
Despite attempts to resuscitate Félicité from a paramedic and single responder medic, she was unfortunately pronounced dead at the scene.
Félicité's death is being treated as 'unexplained' at this time, though it's understood police found no signs of drugs at the address.
A full post-mortem examination and toxicology tests are set to take place.
A Met Police spokesperson said: "Police were called by the London Ambulance Service at 12.52pm to a residential address in SW5.”
The London Ambulance Service said: "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."
Our thoughts are with Félicité's family at this difficult time.
