VIENNA (AP) - "Desperate Housewives" star Eva Longoria , singer Katy Perry and former Baywatch babe Pamela Anderson are in the Austrian capital for a star-studded gala to raise money for people with AIDS.

The trio says they are honored and happy to take part in the Life Ball, which each year attracts thousands of revelers dressed in quirky costumes - and sometimes nothing more than glitter and body paint.

The party in Vienna's city hall kicks off Saturday evening with an extravagant outdoor ceremony that will feature former U.S. President Bill Clinton.
