However, before the big day, the happy couple decided to celebrate with friends in Venice. The Zero Dark Thirty star wore a beautiful knee-length red dress as she walked arm-in-arm with her fiancé, who sported a striped blue shirt and navy blazer. They were also joined by actress Anne Hathaway and her husband Adam Shulman. Hathaway, the 34-year-old star of Les Misérables, wore an airy floral dress paired with baby blue suede sandals.
