No more parties in L.A. - unless Cartier is throwing them. On Friday, the luxury jewelry brand toasted to the launch of the Panthere de Cartier watch with an It Girl-filled bash hosted by Sofia Coppola, Cyrille Vigneron, and Mercedes Abramo at Milk Studios, where guests including starlets and supermodels came out to celebrate. Dakota Johnson, Poppy Delevingne, and Dree Hemingway were among the glamorous guests who enjoyed performances by Alicia Keys, Lion Babe, and Mark Ronson, as well as a firsthand look at plenty of bling.
