Elton John, Liza Minnelli and Donatella Versace were among the stars raising money for Aids causes at Vienna's 13th annual Life Ball on Saturday.

"We're all here because we want to make some noise," Minnelli told reporters. "When it gets quiet, it gets ignored."

The singer joined 4,000 partygoers at Vienna's city hall, transformed into a discotheque for the evening.

Some 35,000 people, many dressed in exotic outfits, gathered outside to party until the early hours.

They were treated to a fashion show that took place on a giant catwalk in the shape of a red Aids ribbon.

Other guests at the event included supermodel Heidi Klum, singer Marianne Faithful and soul star Randy Crawford.

Last year's Life Ball raised 907,000 euros (£623,000) for Aids-related charities.
