From Gwyneth Paltrow to Justin Timberlake, the stars were out in force last night to attend the annual amfAR charity gala event in Los Angeles.

This year's event honoured fashion designer Tom Ford who was the star of the night, with both the man himself in attendance and an array of his designs worn by a long list A-list attendees.

It was undoubtedly Rihanna and Miley Cyrus who stole the show however. Rihanna opted for a nipple pastie, white cutaway gown accessorised with stockings from the spring/summer 2015 Tom Ford collection.

Cyrus went equally risque in another design from this collection; a Fifty Shades of Grey inspired bondage black gown that just about covered her modesty.

The black tie event where tables start in the $15,000 price range, took place at MILK studios in Los Angeles and included a dinner followed by a live auction.

Rihanna was reportedly one of the big bidders at the event, purchasing a pair of $35,000 Harry Winston diamond earrings and splashing a further $100,000 on a signed photograph of Elizabeth Taylor at the Eden Roc by Willy Rizzo.

The Inspiration Gala is an event hosted by the amfAR charity which raises money for Aids research programme. The swanky gala celebrates fashion and style and this year the event was honoring the designer Tom Ford.
