All I will say on the matter is that she has been to LA and New York( and other parts of the world where she isn't famous) again and again since the beginning of her career. Why would she not like how she was treated there all of a sudden?
Sure she would actually be LIVING in America, but gurl is rich enough to get whatever she wants haha. We are getting one side of the story from a provoked friend. And I believe Ayu whole-heartedly when she says her return to Japan was affected by the events of March 11th. Power of Music had too much integrity to just be a lie. Was it the only reason for the divorce? Probably not. But I believe that it played a huge role. This is a common problem with artists who date other artists. Schedules, needing to be in other parts of the world. One that comes to mind is Rebecca Romijn and John Stamos. Rebecca wanted to further her Hollywood career while John wanted to further his Broadway career.
