Someone once told me that a musician has to decide whether they want to be known for their music or their personal lives, because that's what people will care about.

It may be something like this you have in mind:
======================================================
The Choice


The intellect of man is forced to choose
perfection of the life, or of the work,
And if it take the second must refuse
A heavenly mansion, raging in the dark.
When all that story's finished, what's the news?
In luck or out the toil has left its mark:
That old perplexity an empty purse,
Or the day's vanity, the night's remorse.


- William Butler Yeats

Yes, she has chosen to go down a certain path, which in at least the short term will gain much publicity and no doubt a fair bit of money. Whether that turns out to be worth it long term is something only she will be able to decide.

As for 'grooming': a bit of an over reaction, I would say. Pillorying (or worse) for people accused of 'corrupting the youth' is hardly new, but somehow the youth generally seem to get through. Most can tell the difference between life and performance, and art in general is about challenging or exploring perceptions, assumptions and attitudes. Ok, this video is hardly high art, but even so it merits a place on the lower rungs of the ladder.
