"Estrella" is pure late-night reggaeton fantasy: sex, obsession, and zero shame about it. Dalex and the others are basically talking about that one girl they cannot stop thinking about, to the point that he says "tengo un video porno, ella es la estrella" [I have a porn video, she is the star] and keeps "dándole rewind" [hitting rewind] to remember her. The song is all about the physical side of the relationship, replaying what happened in that "viejo motel" [old motel], smoking and getting high while thinking about her, and treating their private sex video like his favorite movie.
The verses go even harder into obsession and possession. Her body feels like a drug to him, "tu cuerpo es como una droga" [your body is like a drug], and he says he already put his "sello" [seal] on it, like she belongs to him. There are a lot of playful, over-the-top lines, like comparing her to Alexa because she always answers him, and saying in the street she is his queen but in bed she turns into "mi Alexis Texas" [my Alexis Texas, a famous porn star]. Ryan Castro even remembers the exact date he met her, "de casualidad la conocí un veintitrés" [by chance I met her on the twenty-third], and brags that the same night they did it more than three times. The whole song is basically one long, explicit memory of secret hotel rooms, sex, alcohol, weed, and a video where she is the star and he never gets tired of watching it again and again.
