With our own Brit girl Alexa leading the pack in a black velvet Chanel dress with cute mini bag worn cross-body, she completed her all-black ensemble with opaques and 70s style sandal wedges. Naomi Watts also scooped top marks for her style, looking chic in a simple shift dress with black shoe-boots, as she posed for pics with partner Liev Schreiber.
But it wasn't all dark hues at the glamorous evening, Liv worked a pretty pink floral ruffled maxi with trench coat, while actress Camilla Belle opted for a bold beaded blue and green floral pattern 60s style dress with blue Rupert Sanderson pumps.
Also joining the fash-pack team were Kim Cattrall, Leelee Sobieski, models Karlie Kloss and Lily Donaldson, and Twlight hottie Kellan Lutz - making it surely the most star-studded event of the festival yet!
