These three leggy beauties attended the “Happy Diamonds Are A Girls Best Friend” Chopard Event during the 2011 Cannes Film Festival last night.

Naomi Campbell: The supermodel wore a sexy black Emilio Pucci mini Fall 2010 dress with Sergio Rossi ‘Asteria’ sandals. She looks radiant. That smile could light up a room.

Uma Thurman: The actress continues her love affair with Dolce & Gabbana by opted to wear the same Dolce & Gabbana lace black dress and the same Giuseppe Zanotti crystal-embellished T-bar sandals she recently worn on the Jimmy Fallon show.

Bar Rafaeli: The model never met a short dress she didn’t like. On this occasion she showed Mr DiCaprio what he’s missing wearing a black and navy blue sequined Roberto Cavalli strapless mini dress. Love the dress, but those shoes are too heavy for this mini.

All the ladies wore Chopard jewels.
