Meh.
I believe in (adult) person's absolute right to do whatever they wish with their own body. ANYTHING. Including removing the limbs, nose, breasts, etc if they wish to, becoming 'Black Alien Project' or this woman. It's their body, their life and their choice. Also all the fillers, botox, teeth and whatnot - personal choice. No one has to like it, except for them.
Do I like it? It's a bit too much. I personally wouldn't do it. But I'm not her. And I actually do like Rick Genest, I think he looks cool.
Will they regret it in the future? Possibly. Maybe. Or maybe not. It's their responsibility and on them. I'm not saying this in a nasty way, but they should make up their minds, stick to it it and accept the responsibility for their choices. Just like any other person.
