Singers Rihanna and Miley Cyrus are no strangers to showing off some skin.
This time, it was at The American Foundation for Aids Research's (amfAR) Inspiration Gala in Los Angeles on Oct 29.
With their risque, "barely-there" outfits, all eyes were certainly on the Umbrella and Wrecking Ball singers for the evening.
The star-studded gala evening also featured various celebities, including supermodel Alessandra Ambrosio, Lea Michele, Milla Jovovich, Gwyneth Paltrow and Michelle Rodriguez.
