I've never gotten the impression that she needs to "get her $hit together". She's never been seen intoxicated (hello, Reese "DO YOU KNOW WHO I AM?!" Witherspoon), nor had DUIs, she isn't rumored to use drugs, she doesn't post endless provocative selfies, or even give interviews all that often.
She's not the most interesting person out there, and she doesn't come across as well read or even that smart in public interviews. If anything to me she comes across as a harmless girl with unique facial features that has managed to figure out how best to style herself and her ubiquitous Smart water bottle. She's crazy wealthy, in great shape, takes vacations with loads of friends, oh yeah, she has a ton of female friends which has been a frequent criticism against Angelina. Overall she's living pretty sweetly. And it's not like she's never had relationships after her big breakup with Brad. Frankly, I admire her for not having kids. Wish she'd just said up front she didn't want them, to help the stigma against those that don't feel that pull. But beyond that, I don't feel sorry for her or pity her now. When Brad left her for Angelina I did, but not this time.
She's very much in control of herself and plays the fame game better than most. I still think there's no way that what she and Justin had was all that special if something as meaningless as location came between them. Even her divorce (if they were really married) will be a breeze, between iron clad prenups and her endless resources.
