KATY Perry, Heidi Klum and Rumer Willis brought the glam at the ninth annual amfAR Gala this evening.
The star-studded bash was held at the Wallis Annenberg Center for the Performing Arts in California and this year, the event honoured singer-songwriter and activist, Katy Perry.
The black-tie event features a cocktail reception, dinner, live auction and special performances - including one by Dame Shirley Bassey.
The gala has raised more than $13 million for HIV and AIDS research and Katy is being honoured alongside Blake Mycoskie for their commitment to the fight against AIDS as well as other humanitarian work.
