“Swift revealed that “You Are in Love” — particularly the line “you’re my best friend” — was inspired by Antonoff’s relationship with then-girlfriend Lena Dunham. “I’ve never had that [in a relationship], so I wrote that song about things that Lena has told me about her and Jack,” Swift told Elle.”
