KEY POINTS:
Sex and the City star Kim Cattrall, fashion icon Linda Evangelista and actress Sharon Stone were among the celebrities attending Vienna's Life Ball, a splashy gala that raises money to fight Aids, at the weekend.
The gala, held in Vienna's historic city hall, is billed as Europe's largest and most spectacular annual charity event dedicated to combating HIV and Aids.
Each year, it attracts thousands of revellers who dance the night away in outlandish outfits - and often nothing more than body paint and glitter.
This year was no different.
Stone, a representative of the American Foundation for Aids Research (amfAR), a nonprofit organisation dedicated to the support of HIV/Aids research, urged people to stand up for themselves and others.
"Words matter ... we can't end Aids if we don't stand up for our humanity," Stone said.
Cattrall, who presented a ¬100,000 ($200,968) prize to CARE Austria for an HIV/Aids project the group runs in Kenya, highlighted the need to protect children from the deadly disease.
Organiser Gery Keszler hopes this year's ball will top last year's ¬1.2 million fundraising record.
