Justin Timberlake got together with his In Time costar Amanda Seyfried at Comic-Con in San Diego yesterday. The duo were there to promote their upcoming film, which was previously titled Now. Justin switched gears for the event since he's been busy with press for Friends With Benefits lately. He and Mila Kunis premiered the movie in NYC earlier this week and Justin Timberlake sat down with Conan O'Brien to talk about the project and also shared his preference for girls who talk dirty, just like Mila's onscreen character. Justin and Mila's film hits theaters today and the reviews of Friends With Benefits are looking good.
