Just when you think Kate Beckinsale looks amazing, as she does, in her stretch pants and white tank top, cause, yep, she does, she goes and bends over to pick up an imaginary pencil and provides what can only be described as the world's greatest encore for the world's hottest MILF. I almost never use the "est", you know that. But these Kate Beckinsale butt pictures seal the back door deal. She is the official queen of Hottie Mom Hill. Long may she reign. Enjoy.
