She seems young and for that, even younger in her maturity. I think she became famous before she was ready for it, and as such, she's making some of the bad decisions that people who are told that they're something special before they realize just how much up to chance it is that anyone gets any sort of attention it is (see also: Jake Paul). I think that eventually, she's either going to grow up a bit and adjust her outlook, or she'll burn herself out, or her fans will become tired of her, or she'll just stop doing her thing.
