Love is in the air for one of the Olsen trolls twins!  We spotted Mary-Kate Olsen this week eating lunch with her boyfriend Nate Lowman.  I didn't think the two of them were capable of emotion; I always just pictured them miming to each other about what the most stylish headband is this season and then remaining mute to the rest of the world. This guy seems like he's great at smoking cigarettes though, so maybe he does speak M-K's language!
