Stars including James Corden, Olly Murs and Charlie Puth have sent their support to Louis Tomlinson following the tragic death of his 18-year-old sister Félicité.

Félicité, a social media influencer, was found dead in her London home on Wednesday after a suspected cardiac arrest.

Actor and talkshow host James Corden said the news was "incredibly sad" and tweeted to Tomlinson that he is "not on your own in this".

Singer Olly Murs also reached out to the former One Direction star saying he is "sending my love to him & all his family right now".

American singer-songwriter Charlie Puth said he is sending "prayers" to Tomlinson and added: "I can't imagine how hard it is right now".

X Factor winners Rak-Su also offered their prayers for the family.

They posted: ''Our condolences and prayers go out the @Louis_Tomlinson and his family at this time (sic)''

Singer Charlie Jones tweeted that he "can't imagine the pain" Tomlinson and his family are going through.

Radio DJ Tom Green tweeted that Tomlinson isn't alone in dealing with the tragedy.

According to The Sun, Louis has been left "devastated and distraught" by the death of his sister, who has been praised as "loveable, caring, bright and beautiful" by "sources close to the One Direction singer".

Her death is being treated as unexplained by police.

In a statement, Scotland Yard said: "Police were called by London Ambulance Service at 12.52 on Wednesday, March 13 to a residential address... following reports of a female in cardiac arrest.

"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.
