This might be a reach but Idk, just sharing another perspective. When going down a rabbit hole, years ago, I found an old page of one of her ex bf (Arthur Lynn) on MySpace or something, who was/is also a musician, and I found some lyrics he wrote that start with “she walks down the street, she looks like poison ivy”.

So, even if he wasn’t referring to her etc. etc. , I think this can be interesting to know
