Hotel heiress Paris Hilton is ditching her night club parties for a glamorous appointment at the Vienna Opera Ball next month. The 25-year-old has been invited to the traditional event as the guest of Viennese socialite Richard Lugner, 74, and has reportedly been paid a staggering $1 million for the appearance.

Lugner's wife Christina told a press conference, "She is a very good advertisement for the Opera Ball."

The real estate mogul's previous celebrity dates have included Faye Dunaway, Sophia Loren and, last year, Carmen Electra.
