To celebrate the launch of its new Panthère de Cartier watches, luxury maison Cartier hosted a stellar party at Milk Studios, Los Angeles.

A-listers turned out en masse – think Sofia Coppola, Sienna Miller, Dakota Johnson, Lily Collins and many more. Songstress Alicia Keys wowed the crowd with her impeccable live performance while Mark Ronson spinned for the party.

The venue was decked out to look like the inside of a jewellery box.
