Either way, it looks like she's no longer dating the guy, which means that this probably will blow over pretty quickly (it's not like what happened with Mari or Miki). The article, IMO makes him a bit of a sleazebag for selling her out like this. He knew when they were going out (if it really was Eri, that is) that she's an idol, and that even without that, it's not right to go blabbing around and selling what should be private photos the way that he did.
