Champagne Problems, Taylor Swift (Splendor in the Grass)

An edit to Champagne Problems by Taylor Swift, featuring Bud (Warren Beatty) and Deanie (Natalie Wood) from the 1961 film Splendor in the Grass. I saw a tweet a year ago suggesting Champagne Problems could be about this film, and I always wanted to make an edit. Alas I never kept the original tweet, so I don't know who to thank for the idea!
