Gwyneth Paltrow and talent agent Bryan Lourd cohosted the 5th annual amfAR LA Inspiration Gala, which honored fashion designer and A Single Man director Tom Ford. Miley Cyrus wore a bondage-style dress that Ford designed, but she wasn’t the only one who showed a lot of skin. Rihanna also left little to the imagination with her gauzy gown. Diana Ross and Paltrow’s ex Chris Martin performed at the event. Other attendees included Justin Timberlake, Lea Michelle, Kelly Obsorne and Rita Wilson.
