It's not her age that's the problem, it's the fact that she's acting like a total slut!
Of course 17-year-old's are sexual, but there's a time and a place!
At a party or something, fine. But taking pics like this with an old man (and he IS, compared to her. He's literally old enough to be her dad)? Not cool.
She's a Disney star, for Christ's sake, and she just needs to accept that or go away 'cause she's not talented enough to do anything else.. expect maybe enter the porn industry.
