Stars! They're just like us! They run funny. They take snack breaks. And when they're posing for sexy photo shoots, they head straight for the loo and hop in the tub! Here's "Mad Men"'s January Jones, lounging in a tub full of flowers for VioletGrey.com. She didn't even bother to take off her diamonds, because that's how the glamorous do. January is not the only one getting squeaky clean. Here are 18 other stars posing in or on bathtubs -- bubbles are a bonus.
