Louis Tomlinson's sister Félicite died of a suspected cardiac arrest at her London apartment on March 13 at the age of 18
“Just wanted to thank everyone for their lovely words over the past couple of weeks,” the 27-year-old former One Direction singer shared on Twitter Wednesday morning. “Back in the studio today to vocal something I wrote a few months ago. Sending you all loads of love x.”
Before her sudden death, Félicité, who was also known as Fizzy, worked as a model and influencer with over one million followers on Instagram.
On March 13, she passed out after a suspected cardiac arrest at her studio apartment in Earls Court, West London, according to The Sun.
A friend, who was with Félicité at the time of the incident, immediately dialed 911.
When emergency responders arrived to the home they attempted to resuscitate Félicité; however, it was too late. She was pronounced dead at the scene, The Sun and The Daily Star report.
“Police were called by London Ambulance Service at 12:52hrs on Wednesday, 13 March to a residential address … following reports of a female in cardiac arrest,” the Metropolitan Police previously told PEOPLE in a statement. “Officers attended. A female believed to be aged 18 was pronounced dead at the scene. At this stage, the death is being treated as unexplained. A post-mortem examination will take place in due course. Enquiries continue.”

Félicité’s death came after their mother Johannah Deakin died of leukemia on Dec. 7, 2016. She was 43. Just weeks before his sister’s death, Louis paid tribute to his late mother in “Two of Us” — the first single off his debut solo album.
The song is a deeply personal and emotional pop ballad about the bond the two have, even after her death.
It begins by Tomlinson addressing Deakin directly, admitting that the day she died he wished “it was me instead.” However, after mourning her loss, Tomlinson began to take the lessons he learned from her and focus on the positives.
“I will keep you day and night, here until the day I die / I’ll be living, one life for the two of us,” he sings, in the chorus. “I will be best of me, always keep you next to me / I’ll be living one life for the two of us.”
