"Les Miserables" actress Amanda Seyfried leaves Claridges hotel in London, England on December 7, 2012. Though Amanda has starred in two play adaptations, "Mamma Mia" and "Les Mis," but admitted she could never perform them on Broadway. "I'd like to do it, but I just don't see myself on stage singing. I don't think I'm capable, or have that kind of stamina to be on stage every night. I really doubt I will, ever."
