Louis Tomlinson's younger sister, Félicité Tomlinson, has been found dead at the age of 18, The Sun reports.
Félicité, a model and social media influencer with over 1.3 million Instagram followers, reportedly collapsed after a suspected heart attack at her apartment in London. She last shared a photo to Instagram on Sunday, March 10. In the picture, Félicité can be seen sitting on the floor as she takes a selfie. "Don't know why I look so shocked," she captioned the post.
The heartbreaking news comes just two years after Félicité and Louis' mum, Johannah Deakin, passed away after a long battle with leukaemia. It was exactly one week ago that the 27-year-old One Direction star released an emotional new song about his mother's death called 'Two of Us.'
In an interview with Radio 1 Newsbeat, Louis shared how he used to call his mum for advice, which he mentions in the opening of the song."It was something I needed to get off my chest," he said. "I used to lean on my mum for a lot of things - anytime I needed advice on something she would be the first call I made."
The Tomlinson family are yet to comment on Félicité's death. Our thoughts are with her family and friends.
