Tragedy has struck Louis Tomlinson and his family.
Félicité Tomlinson, the 18-year old sister of this beloved artist, collapsed on Wednesday at her apartment in London.
Someone reportedly found her body and called the paramedics, who attempted to revive the teenager. But it was too late. She was pronounced dead at the scene.
According to TMZ, Félicité showed no warning signs of any kind there was no prior history of heart trouble. She did, however, suffer from sciatica.
(This a type of to back pain caused by a problem with the sciatic nerve, which runs from the lower back down the back of each leg.
To be clear, however, there's no reason to believe right now that this condition contributed to her passing.)
"Police are in the process of informing her next of kin," a statement from the local police reads, adding:
"At this stage the death is being treated as unexplained. A post-mortem examination will take place in due course."
Félicité last posted a photo to Instagram on Sunday, March 10. In the above image, she can be seen sitting on the floor as she snaps a selfie.
"Don't know why I look so shocked [heart emoji]," she captioned the picture.
Félicité worked as a model and social media influencer; she had over 1.3 million Instagram followers, for instance.
She also a fashiond designer and, according to insiders, was planning to release a book of poetry at some point down the line.
Back in January of this year, she posted on social media she had stopped drinking and also stopped smoking cigarettes.
TMZ writes that Louis and Félicité were especially close, regularly seeing each other when he was in London.
This awful news comes just over two years after Félicité and Louis' mom, Johannah Deakin, died after a long battle with leukemia.
It was exactly one week ago that the 27-year-old One Direction singer came out an emotional new song about his mother's death called "Two of Us."
In this tribute track, he sings directly to Johannah, telling her how much he misses her and how he's living his life for the "two of us," continuing as follows:
You'll never know how much I miss you/The day that they took you, I wish it was me instead. But you once told me don't give up/You can do it day by day/And diamonds they don't turn to dust or fade away.
Louis and Félicité were two of seven siblings, with the former being the oldest.
Neither Tomlinson nor anyone from his team has commented yet on this tragedy.
We send our condolences to his friends, family members and loved ones.
May Félicité Tomlinson rest in peace.
