I can see why anyone would think that but, IMO, I don't think that's the case. In her mind, Maradonia is her life's crowning achievement; the proof that she truly is a talented, gifted individual, and the special-est snowflake of them all.
I mean, any simple plebeian can write rap songs, model on a runway/calendar, act as a mermaid part-time, etc. etc. But getting a novel published and having a (faux) high budget film made? A work of a true genius! -- if you ignore the absurd amount of money her parents threw at her to get Maradonia published, marketed and made into a movie.
I bet, like all teenagers of a certain age, she simply got bored (probably cause it wasn't giving her the instant adoration and praise that she oh so deserved) and simply shifted her interests to rapping, modelling, preaching or whatever the hell she's doing now. Which should serve as a moral to all parents everywhere not to invest too much or harp on a child's interest or hobby.
