After playing Linda Lovelace, there’s not much that makes Amanda Seyfried flinch. And yesterday (September 24) the “Big Love” babe had to go without trousers as she filmed her new project.

Seyfried pranced around in her underwear on the set of “While We’re Young” in New York City, and given the fall temperatures it was likely a chilly endeavor.

However, Amanda had the support of director Noah Baumbach and nearby costars Ben Stiller, Naomi Watts, and Adam Driver, so it was all good.

Per the synopsis, “While We’re Young” is about “an uptight documentary filmmaker and his wife as they find their lives loosened up a bit after befriending a free-spirited younger couple.”
