In it, she specifically references a "blonde girl" that's "so much older" than her, whom she thinks is the reason why the boy in the song (probably Joshua) left her.
Enter Sabrina Carpenter, the rumored "blonde girl" Olivia is reffering to, who just last week released her own song "Skin," seemingly addressing the drama.
There are honestly a bucketload of lyrics in "Skin" that could be referencing this drama, but I'd like to hone in on these two: "maybe blonde was the only rhyme" and "you're telling it how you see it, like truth is whatever you decide."
Got it? OK, good. That brings us to now: Disney's potential involvement.
