Mary-Kate and Ashley Olsen arrived at LAX in separate cars a few hours apart yesterday on their way out of town. The blond twins were both incognito, but it's hard to miss MK in her drapey clothing and Ashley with her big Starbucks. MK and Ashley have been making the rounds promoting Influence and earlier this week Mary-Kate made an awesome guest appearance on Samantha Who?. Not only did she do a fantastic job on the show, but she even dressed quintessentially her. Both Olsens seem happy in their relationships and successful in all their projects these days, growing up into impressive women each in her own right.
