She Filled Her Pool With Champagne
Swift sings that Harkness, "Filled the pool with champagne and swam with the big names." And while the image of a socialite literally swimming in bubbly may seem a little too on the nose, it's not quite a metaphor. According to the book Blue Blood about her life, Harkness was known to clean her pool out with Dom Perignon. Whether she ever actually swam in it, though, is up for debate.
