Cape Town – Louis Tomlinson's family have suffered another tragic loss after his sister, Félicité was pronounced dead on Wednesday.
E! News confirms the 18-year-old social media influencer collapsed after a suspected heart attack at her apartment in London.
According to the report Félicité was pronounced dead at the scene after London Ambulance Services responded to a call about a female in cardiac arrest.
A statement from the Metropolitan Police Service reads: "Police are in the process of informing her next of kin. At this stage the death is being treated as unexplained. A post-mortem examination will take place in due course."
The devastating news comes just over two years after Louis and Félicité's mom lost her battle with leukemia.
Johannah Deakin died on 7 December 2016 after being diagnosed with an aggressive form of the cancer earlier that year.
