Oh Miley. Miley, Miley, Miley. I have never watched Hannah Montana, I have never seen a movie that stars Miley, but I still know all about her life too. For a while it seemed like maybe she'd chilled on her shenanigans – wildly inappropriate photo shoots, even more inappropriate candid shots, and on, and on, and on – and then she shows up on video. Smoking salvia. Out of a bong. That's not the only thing that shot her into the top lists for just about every search engine, but it's one of them.
