Mary-Kate Olsen may have her hands full both literally and figuratively, but the Olsen girls are expanding their empire yet again. They're set to publish their very first coffee table book called Influence. According to Mary-Kate, the book will feature creative minds that the twins feel reflect their generation saying, “Ashley and I interviewed the people who have inspired us, with the hope that they will inspire and teach others." Some of the featured artists include Christian Louboutin, Lauren Hutton, and, of course, unseen photos of the twins themselves. MK and A have grown out of their tween taste, so we'll see if their appeal has grown up too.
