Paris Hilton will be the "date" of a wealthy Austrian industrialist at the Vienna Opera Ball - the highlight of the country's social season - and will receive a reported $1 million for attending the event. Richard Lugner and his wife have a custom of inviting celebrity guests to the ball, and in his past dates include Pamela Anderson, Sophia Loren, Geri Halliwell and Sarah Ferguson. Hilton is allowed to bring her parents and three other guests to the event, but her chaperones won't include Britney Spears - who was knocked off the list of invitees after the once-fast friends had a falling out. When asked about Spears's un-vite, Lugner's wife said, "They unfortunately do not get along anymore."source, source
