I don't see why anyone is shocked or up in arms about this. She's not doing anything differently than people like Katy Perry/Britney Spears/Kelly Clarkson/etc. have done. She just happens to have a history in the pop-punk scene.
I'm not interested in any of her past, present, or future music but she seems like a nice girl. She definitely doesn't deserve all this crap, especially when most of the people on here worship pop acts that she has stated she wants to be like.
I'll give her credit for being completely upfront about everything and not trying to hide her intentions for what she's going for. She's definitly shooting for the stars but really seems down to earth in the sense of being real with her fans.
