Fun Behind-the-Scenes Pictures From Stars This Week

I have a lot of fun watching what happens on screen, but I imagine that once the cameras stop rolling on sets like Glee and Whitney, the stars really let loose. Heck, it appears they even smile on the set of American Horror Story! This week, quite a few actors let their guards down and shared candid pictures of themselves hanging out between takes. Check out John Krasinski's tough look on The Office and more surprising snapshots!
