You might know her from 'Grey's Anatomy', but Katherine Heigl's is the only anatomy we're interested in checking out.

She's been in plenty of television shows and films like '27 Dresses' and 'Life as We Know It', but she started her professional life as a model. And if you take a look at her, it's not hard to see why she'd be a model. Not only is she beautiful, but she's also a talented actor and producer. We love hotties, but we love them even more when they bring several talents to the table.

In the gallery below, you'll see Miss Heigl's assets in full force. These animated GIFs help offer a lot of bounce factor so you can appreciate her more physical charms as well.
