Amanda Seyfried is currently filming Noah Baumbach's "While We're Young" in New York, and apparently one scene calls for a pantsless look. The "Les Miserables" alum stars alongside Ben Stiller, Naomi Watts and "Girls" standout Adam Driver in the movie, in which an older couple (Stiller and Watts) meet and become friends with a younger couple (Driver and Seyfried).
Take a look at the on-set pics below.
