I just read Billy Ray Cyrus' (Miley Cyrus' dad) interview that he did in GQ. He was talking about how 'Hannah Montana' ruined his family and how he now wishes that it never happened. He also spoke about how he didn't attend Miley's 18th birthday because she chose to have it in a bar (in the States it's 21 and over) and he is sick of taking the blame for all her bad decisions (i.e. the night she decided to use the bong). Somewhere in the middle he mentions how their Faith was challenged in the process and how Miley changed. He also mentions how his family is under attack by Satan and he is scared for his daughter.

You can read the full interview here so you can understand a little bit of my thoughts on it...
