Keira Knightley couldnt help but smile as she strolled through downtown Manhattan this weekend. The reason for her cheer? Thats probably thanks to fiancé James Righton, but we have to give some credit to Knightleys light and lovely Erdem floral dress and tiny Chanel handbag too.
Also brightening the weekend with her grin was Jaime King, who wore Stella McCartneys blue and black brocade blouse-skirt combo to the CBS Summer Tour party in Los Angeles. Monochrome queens Rachel Bilson and Emmy Rossum also attended the event.
And whats that? Rihanna, covered up? The singer donned a Grecian-style blue flower-printed white chiffon dress for a yacht trip in the south of France.
