Why even bother wearing clothes at all? The amfAR Inspiration Gala held in Los Angeles last night was a successful, star-studded event with celebs like Justin Timberlake, Lea Michele and Gwyneth Paltrow in attendance. But most of the attention was focused on Miley Cyrus and Rihanna and their, err… lack of clothing.

Miley looked like a fierce dominatrix in her barely there dress, with only tiny black straps covering her nipples. While in comparison, Rihanna looked fully clothed, the singer had nothing but purple sequins covering her lady-parts.

Check out Miley, Rihanna and 8 other stars in their most risqué outfits ever!
