Miley seems jealous she does this a lot with Selena as well... she mimics some of her photo's and lets not forget when she bullied demi and selena with that youtube video when she was 15 or something lol
Miley obviously does those things for attention. It's not the first time she posts things like that but this time she got the attention she was looking for. Her Instagram is basically an attention seaking mess. Idg your point.
