Hilary Duff supposedly wrote a young adult novel (yeah, and Snooki wrote hers all by herself too), so this might have been the reason why she was in Paris. Because the French are just dying to lap up schmaltzy teen lit written by Lizzie Maguire. I might not believe that but the chick has never looked better since marrying Comrie, so I'm willing to place money that those two actually love each other. For now.
