It must be difficult to be a celebrity, considering that every move you make is promptly dissected by people you'll never meet. With that said... What is up, Mary-Kate Olsen? Shown here at a recent soiree in London, she looks a little less presentable than usual. There's got to be an explanation for her matted-down hair. Maybe it was raining outside? Maybe she had hat head? Maybe she just took a jog? Maybe we'll never know, but my fingers are crossed that this stylish twin's just having a rough day.
