Katherine Heigl spends a lot of time on-screen removing articles of clothing. We think this is indisputably a good thing, so we decided to collect a bunch of that here.

(Some of the GIFs are of her after she's already taken something off. We didn't think you'd mind.) Enjoy the Grey's Anatomy and Knocked Up starlet as she does her best to unburden her hot body of all that unnecessary apparel:
