For celebrities this week, it's not all arrests and unfortunate selfies. Keira Knightley, for one, has great news: she and fiancée James Righton got married on Saturday. The two wed in a low-key town hall ceremony in Mazan, France. But that doesn't mean it wasn't classy: Knightley wore a Chanel dress by Karl Lagerfeld during the ceremony, performed by the town's mayor. The couple reportedly drove off in a battered Renault —on their way to a lavish reception at a friend's vast vineyard estate nearby, where scores of high-profile guests had gathered to celebrate. These are celebrities we're talking about, after all.
