BREAKING: Louis Tomlinson's Sister Félicité Tomlinson Found Dead at 18

From Seventeen

• Former One Direction Louis Tomlinson's sister has been reportedly found dead at the age of 18.

• This follows the death of his mother a little over 2 years ago.

• Fans are mourning for Louis during this time.

Former One Directioner Louis Tomlinson is mourning the death of his sister, according to multiple reports. Félicité Tomlinson, who has been found dead at the age of 18, reportedly suffered a heart attack and died at her home in London on Wednesday, TMZ reports.

Félicité was a social media influencer, with over a million Instagram followers and a lot of adoring fans. She was allegedly planning to launch a fashion line under her nickname, Fizzy, in the coming year.

In her last post, which went up 4 days ago, she said: "Don’t know why I look so shocked." In the image, she is sitting on the floor in a black top and jeans.

According to TMZ, "sources have said that Félicité had absolutely no warning signs and they knew of no prior history of heart trouble."

According to E! News, The Metropolitan Police Service says "that police were called by London Ambulance Service on Wednesday to a residential address following reports of a female in cardiac arrest. Officers attended, and a female believed to be aged 18 was pronounced dead at the scene."

The statement from police obtained by E! news goes on: "At this stage the death is being treated as unexplained. A post-mortem examination will take place in due course."

This is not Louis' first experience with loss, sadly. A little over two years ago, Félicité and Louis' mom, Johannah Deakin, passed away from leukemia. This loss inspired Louis to write a song in honor of his mother called "Two of Us."

Fans are also reaching out to Louis on social media to extend their condolences.

One fan wrote: "Every single thought and prayer tonight is going out to @Louis_Tomlinson.
The amount this man has gone through is unfair and he deserves every ounce of credit for still standing. Terribly sorry for your loss, may she rest in peace."

Another said: "I'm praying that Louis will never lose the hope that he always had. I wish he never loses what he holds on to. I wish he stays strong through it all even though the world is too tough for him. I hope this sh*tty world won't change Louis Tomlinson.

And another fan went on: "I'm so sorry Louis. This is a hard time for you right now. She was taken way to young. Take your time, heal and be with loved ones. I'm sorry you were taken so soon babygirl. No one deserves this #Rip @Louis_Tomlinson."

Louis has yet to release a personal statement, and the One Direction boys have yet to say anything public about this tragedy. We're just wishing him and his family peace and healing at this time.
