Also seeing how she's losing followers on Instagram, and how little she posts, her popularity doesn't seem to be a concern for her. She probably sees passes as some easy money, before settling down with her BF.
Well, if you compare her to Angel polikarpova, which is what you're describing. They couldn't be more different in character, and personality.
