The original Sixties wildchild Marianne Faithfull has slammed Miley Cyrus and Rihanna as "rubbishy sluts" in an interview ahead of the release of her new album. http://www.independent.co.uk/video/?videoid=3800608527001
I think she is in the right to do that. I remember hearing that Miley's twerking or whatever caused some tension with Mexico and their government opened a federal investigation against her.
