What's more fabulous than a party thrown by Karl Lagerfeld? A party thrown by Karl Lagerfeld in Saint Tropez! Diane Kruger, Joshua Jackson, Vanessa Paradis and Karolina Kurkova were among the stylish guests invited to the south of France to celebrate the debut of Lagerfeld's new short film, Remember Now, and see his Chanel 2010 resort collection. Kruger, in a white Chanel skirt, fedora and ribbon-tied braid, and Jackson, in a festive pastel shirt and shades, played bocce ball and sipped vino at the outdoor party held at Place de Lices (a gorgeous tree-lined open-air market).Their adorable springtime style easily won them the title of night's cutest couple!
