Paris's frothy, pink aesthetic aligns with the movie, but, like Promising Young Woman, it belies hidden depths and real vulnerability and pain.
At the height of her it girl years — when "Stars Are Blind" was released — Paris and everything she did and everything that happened to her were, on the whole, treated as a joke. This even applied to the abuse she experienced, including the revenge porn her ex released that featured footage of her when she was just 18. Paris has since spoken repeatedly about the trauma this caused her, as well as other abuse she has experienced.
Her story is extremely relevant to the one being told in Promising Young Woman, and the use of her song from that era is a reminder of the way the conversation has shifted in some ways — but, combined with the narrative of the film, also reinforces how far we still have to go.
