Pictures of Amanda Seyfried, Max Irons, and Shiloh Fernandez at the London Screening of Red Riding Hood

Amanda Seyfried slipped into a sexy LBD for today's London screening of Red Riding Hood. She's been in Europe since Sunday, when she touched down in Paris with her boyfriend, Ryan Phillippe, and his The Lincoln Lawyer costar Matthew McConaughey. The trio left the airport together, but it was just Amanda and Ryan who were caught taking a romantic stroll under the Eiffel Tower on Monday. Matthew and Ryan relocated to Berlin yesterday while she traveled south to catch up with her hot costars Max Irons and Shiloh Fernandez in France.
