THis is her edgy boudnary pushing pop period. She'll probably twerk on Futures dikk in a video, then in a couple years after she milks it, she'll go back to safe white big titty beat off-material pop star.
basically...the majority of them do this shyt: miley being the latest example....anyway, she fukked up by going at taylor swift, so she going this route to get through this period, till she makes the change you said...
side note: speaking of taylor swift, it's gonna be interesting to see the reaction if she ever goes through her period like this...
