People would be so much more likeable if they could just do a regular smile have a little humility. I can't stand people that try too be cool and do retarded quirky shit like that.
People with ugly mouths don't look better when they smile; it actually accentuates the design flaws in their face, teeth, or gums. That's why she pulls those faces to begin with. Personally, just an expressionless face would be a lot better on her.
Women don't know the meaning of humility, least of all semi-famous ones that receive an endless stream of adulation, hero-worship, idolization, and flattery via social media, e-mails, calls, video comments, etc. She's an egomaniac for the same reason Pink or Katy Perry are. To be humble, you basically need to be big enough to realize how small you are in the scheme of life, or have had your life destroyed to a crisp and had to built it back up as best you can. That's not something she's ever going have to deal with.
