Billionaire Richard Lugner has died at the age of 91 due to health problems.
According to several sources, the Austrian construction magnate died in his country house in Vienna.
Just two months ago, Lugner married his sixth wife, 42-year-old actress Simone Reilaender, who is 49 years his junior.
He was known for building the Lugner City shopping mall in Vienna in the 1990s, and was also notorious for the celebrity friends he was often seen with at parties.
Lugner is said to have paid large sums of money to stars such as Kim Kardashian and Paris Hilton to be with him at important events.
