Mary-Kate and Ashley Olsen turn 26 today! We love the Olsen Twins—we've seen all of their silly movies, read all of their mystery book series, and ogled all of their gorgeous clothes. And we love that they went from being child stars to being successful, serious fashion designers. Click through this slideshow to see the twins over the years—happy birthday, Mary-Kate and Ashley!
