Nikki acts more, way more, and she also calls herself and her fans barbies. She takes pride in the fake shit as part of her character, along with all the crazy voice pitching. You can knock her for not being a role model. . . Nah, I'm not giving you that one lol

Bottom line, Nikki has to be more than another Black woman rapping to push records, hence all the costumes, accents, etc

Iggy has to be considered "down" so she has to imitate what would be considered regular for Nikki
