It turns out that dating an Olsen twin does not scar you for life. Justin Bartha has moved on from Ashley Olsen to trainer, Lia Smith (above). The couple have been dating for a little while because Lia brought Justin home with her for the holidays. Of course, when home is Hawaii it is a whole lot easier for a guy to say, “Sure, I would love to come see your family.” Justin has had quite the spectrum in girlfriends. When you go from Scarlett Johansson to Ashley Olsen, you have pretty much run from one end to the other there.
