The Weekend's Best Dressed: Beyonce In Mary Katrantzou, Gemma Arterton In Marios Schwab And Marion Cotillard In Christian Dior

We've already brought you all the hottest MTV Europe Music Awards looks today, from Rita Ora's dramatic Marchesa gown to Heidi Klum's eight Versace costume changes, but there were many other fancy shindigs hosted across the globe this weekend. Rachel Bilson invited the Hollywood glossy posse including Lauren Conrad and Jaime King to join her at a party to celebrate the one year anniversary of her footwear collection ShoeMint along with her collaborator and stylist Nicole Chavez. RB looked super cute in a floor-length shirt dress while LC provided some OC chic in a nude lace baby doll dress and matching heels. Across the country in New York City Cameron Diaz wore a strapless Lanvin number for the launch of TAG Heuer LINK Lady while Elle Fanning attended a 'Ginger and Rosa' screening in a black dress and satin pink shoes. In Europe most A-list stars decamped to Franfurt for the EMAs, but Gemma Arterton and Amber Le Bon brought the glam factor to the UK capital for the PeaceEarth Foundation Fundraising Gala. And let's not forget Beyonce in Mary Katrantzou. Fierce!
