This is like what happened with Kago all over again for me. You think about what the girls look like nude, and when you finally do see it, it's rather weird. Shadowstar explained the reasoning behind it pretty well, so I can see why she'd do it for artistic reasons rather than to stir up some controversy and get back in the spotlight. But then, I dunno, I still find it quite unnecessary as it might probably attract the wrong set of fans rather than ones that want to take her as a credible artist.
Seems to me that if any H!P girls, current or otherwise, want to get rid of their idol image, the quick and easy way of doing it is to show some (more) skin. you hear that Aya??
