Tipycal 3w2 So/Sx. ESFJ. Same type than Taylor Swift.
ESFJ may not be a bad call. I prefer that over ENFJ.
[Edit - ISFJ. 'ISFJs need positive feedback from others. In the absence of positive feedback, or in the face of criticism, the ISFJ gets discouraged, and may even become depressed. When down on themselves or under great stress, the ISFJ begins to imagine all of the things that might go critically wrong in their life. They have strong feelings of inadequacy, and become convinced that "everything is all wrong", or "I can't do anything right".' Personalitypage.com]
However, if you read Personality Types, pp 130-131, you will see that Selena Gomez is clearly a 3w4 ("The Professional"). Selena Gomez is so perfect, she is boring. A 3w4 role-model for kids. Her strong reaction to helpful criticism reveals her 4-ish sensitivity. She lacks the interpersonal characteristics of the 2-wing, but focuses mostly on her own self-perfection in her external pursuits.
[Edit - her strong reaction is not against the criticism, or the person doing the criticizing. It is focused on herself, i.e, introjection.]
As for Instinctual stacking, Selena Gomez does not desire the high social standing of the Type 3 So. As she says in the interview above, "I'm just a normal person." Sp/Sx or Sx/Sp. The Sx/Sp 3's especially hate the Type 3 image.
