Blake Lively directed the music video for Taylor Swift’s song “I Bet You Think About Me,” a from-the-vault track released on Red (Taylor’s Version). Lively and Swift cowrote the video’s treatment, which sees Swift crashing the wedding of an ex, played by Miles Teller. It’s a cheeky video, and if you pay attention, there’s a reference to that scarf from “All Too Well.” 

It happens around the two-minute mark, when Swift gives Teller’s new bride a present in a red box: a red scarf. Said bride then drapes the scarf over her neck as wedding guests look on lovingly. Watch it for yourself, below: 

For those unfamiliar with the red scarf, it’s first mentioned in Swift’s song  “All Too Well,” largely believed to be about her ex, Jake Gyllenhaal. “I left my scarf there at your sister’s house /
And you’ve still got it in your drawer even now,” Swift sings. 

Interest in the scarf resurged on November 12 when Swift rereleased Red and with it a 10-minute version of “All Too Well.” The pop icon directed a short film to accompany the new extended song, and the scarf plays a major role in it.
