I think her stock has just gone. While dressing 15 and acting near enough this swearing will only cause her problems. Although she is twenty she has marketed herself and her music to the tween existence instead of the young woman she is.

These Mariah comparisons are kinda annoying because the only thing they have in common is a singing style, but Mariah has much more layers and diversity to her voice where Ariana is just 1 block tone.
