A grieving Louis Tomlinson has tweeted for the first time since the sudden death of his 18-year-old sister Felicite last month.

“Just wanted to thank everyone for their lovely words over the past couple of weeks,” Tomlinson told his followers.

“Back in the studio today to vocal something I wrote a few months ago. Sending you all loads of love x”

Tragedy struck Louis and his family on March 13 when emergency services were called to a London residence after Felicite suffered a cardiac arrest.

It’s not yet known what may have caused Felicite, an influencer and aspiring fashion designer, to have a heart attack.

The tragic news comes just three years after Louis and his siblings lost their mother, Johannah Deakin, to leukaemia.

In an Instagram post after Felicite’s death, Louis’s sister Daisy wrote: “Mama needed you. I hope you are happier up there with her. I have two angels now, watching over me.”

Just a week before Felicite’s untimely death, Louis released a song about his mother called Two Of Us, in which he sings “I’ll be living one life for the two of us.”
