Showing off their tanned and toned pins were Gossip Girl stars Blake Lively, wearing Michael Kors, and Leighton Meester who sparkled in Balmain. A line-up of ELLE cover stars turned out - current star Rosie Huntington Whiteley opted for a Dolce and Gabbanatiger print dress, Emma Watson chose a white Marchesa mini, Kristen Stewart sported a red bandeau dress by Balmain and Reese Witherspoon wore a figure-hugging leopard print number.
Cameron Diaz and Elle Fanning both ditch their dress and sported playsuits instead - Elle's pretty floral creation was from D&G, while Cameron picked a more classic black 3.1 Phillip Lim style. And Hailee Steinfeld bucked the trend altogether by covering up her legs - she sported a stylish trouser suit by Louis Vuitton.
