I first saw this beautiful actress on the movie "Troy." You know the one from a few years back with Brad Pitt, Eric Bana, and Legolas from Lord of the Rings? She's been in a bunch of stuff since then, including Wicker Park, both National Treasure movies, and Inglorious Basterds.
She's been the ambassador of Jaeger Le Coultre (say it with a French accent or it doesn't count) for a few years now. Here's a watch she was caught wearing a little while back. It's the sort of layered/multi-strap look that's coming in right now.
