Baby put on heart-shaped sunglasses
The “heart shaped sunglasses” are a reference to a poster for Lolita (1962), the original novel being by Vladimir Nabokov, which explores the themes of loss of innocence in humans. Lana even has a song called Lolita!
In Lolita, Lolita finds herself curious about something she shouldn’t be — her stepfather. Just as how Lana shouldn’t be pursuing this bad guy.
Also she really does wear heart-shaped sunglasses.
