Shock value sis. She just wants people to keep talking about her and the only outlet she has is Twitter. I still am suspicious of her true intentions behind dragging Iggy Azalea.
Miley needs to drop this mess of an image she has before MC5 starts. It worked for Bangerz but it will backfire if she continues, people are bored of it. Honestly, the most shocking thing she can do just now is appear with her long, brown hair again. That will surely get people talking.
