Talking about Miley Cyrus's video "we can't stop"

It was a big shock when I first  watched it, I wondered what the hell is that supposed to say to the fans? That the real Miley is a b##ch? I mean the video doesn't even match with the song, the song is good, good lyrics, instrumentals etc.. but the video is a drama! It was supposed to show teenagers having  fun, good time, parties  all the time, but this one sounds like: " hey look at me I'm Miley, I grew up now, I'm done being that little girl you knew in Hannah Montana. This is  what I really  am a teen who likes partying and  doing the b##ch.
What do you think?
