I know I'm a tad bit late on this whole topic but I still had to put my input. As Miley reports she is not trying to act or be slutty just to sell her music. Which I believe is true. Think about it her previous albums sold really well before all this so why would she need something else to help sell? In my opinion I think she is just transitioning into the adult world.
No she's not going to end up with a sex tape or on Playboy but I do think she is going into this stage very well. Some Child stars kind of lose themselves a bit when they try to get into that adult phase but I really don't think Miley will have a hard time with that. People say that she's growing up too fast what she's doing isn't good for her career and blah blah blah. How do you know whats good for her? Only she knows. She knows what she wants and she knows she has to work for it but at the same time she is staying true to herself. Plus, you really didn't expect her to stay little old Hannah Montana forever did you?
