Rachel Bilson and Hayden Christensen are currently in France, where they attended the French Open last Friday alongside Eva Longoria-Parker and Tony Parker. Rachel's rumoured to be there to shoot a new advert for Lacoste — Hayden's wearing a shirt by the company in these pics — and the couple took in a few sights as they wandered around the city in the sunshine. The camera around Hayden's neck definitely adds to their tourist look — what an adorable couple!
