Former Miss Teen Universe Lotte van der Zee has died at the age of 20 in Munich after suffering a fatal heart attack, media reports said Friday.

The Dutch model was in Austria with her family on a skiing trip when she suddenly fell ill, according to her parents' statement.

She spent two weeks in a coma before life support was withdrawn on Wednesday.

Sharing a photo of the model on their Instagram account, the parents wrote: "Our pearl, our everything passed away on Wednesday evening March 6 at 10:47 p.m. It is incredibly surreal that our dearly beloved Lotte is not around us anymore. Our hearts are truly broken. We would like to thank you all again for all the support and heartwarming messages."

Tests are still being carried out to determine what caused the model's heart attack, the family said.
