(Meredith) -- Felicite Tomlinson, the 18-year-old sister of One Direction member Louis Tomlinson, has died after suffering a heart attack, according to TMZ.
Felicite died Wednesday at her apartment in London. TMZ reports she collapsed from a heart attack and someone else in the apartment called for an ambulance, but she was pronounced dead at the scene when paramedics arrived.
Felicite was a fashion designer, model and Instagram influencer with more than 1.3 million followers.
The loss of Louis' sister comes just over two years after the siblings lost their mother to a long battle with leukemia. Last week, Louis released an emotional new song about his mom's death, titled "Two of Us."
Louis and Felicite have five other siblings.
