I'm not a huge Miley fan, but I don't hate her in the least bit. Seriously though. What you said is the easiest thing to do.

Ignore it. Well, yeah sometimes that's hard. But try not to pay attention to it. There's no point. People are like 'she's 15 what's wrong with her?' The fact is, she's 15, she'll make dumb mistakes like this, I know I made stupid mistakes when I was 15. People may be like 'she's not a role model now' But do you really want your daughters looking up to someone who is a cookie cutter version of something. Someone who tries to be perfect, and never do anything wrong? That's boring, and no one is like that. This way she shows people she made mistakes. It happens. No one's perfect.
