Perhaps, if you are old enough to cause a semi-stir when you pose semi-nude for a famous photographer, it is officially time to pack it in as a tween idol. Unless of course, you're the children of Sally Mann, but as far as I know, they were never tween idols.
Yes, Miley. I am looking at you.
Note to Disney: Can I have an ETA on the timeline for rolling out the next new tween entertainment/marketing sensation?
