It seems like all sensations end up turning into embarassments. Back in the late 1990s and early 2000s, Britney Spears was worshipped, and I actually thought she was hot. Now, her career is ruined, perhaps irretrievably so, and she's sent to the hospital every 2 weeks because of drug overdose and other health problems. And not to mention how high she looks in all of her pictures. And there are plenty of other celebrities whose lives are out of control, such as Lindsay Lohan, Paris Hilton, and many others.
But anyways, back on topic. She can't expect to keep this up much longer. No one has a perfect life, and in the celebrity world, your life will likely spiral out of control as we've all seen.
But yeah, she'll probably endure some rough times soon. I never want anyone to have crappy lives, and I'm not saying I want Miley's life to be ruined, but that's my prediction.
