Hypothetical scenario; you used to be a child star. Maybe you were on a Nickelodeon or Disney Channel show. Now that you’re in your late teens / early 20s, it’s time to rebrand. As the OG teeny bopper said, you’re “not a girl, not yet a woman”. You’re a human adult, and it’s time to show the public that you’re all grown up, whilst still remaining in the public eye.
What’s the next step? Maybe some emotionally mature stripped-down music, maybe some Oscar Bait-y roles, or maybe some good old-fashioned cultural appropriation.
