The music video tells the story of a loner high school girl who suspects that her father -- who teaches at the school -- is having an affair with a Farrah Fawcett look-alike teacher, who just so happens to be his daughter's crush. Fans are saying they spot Swift when Gomez, in the role of the high school girl, is alone in her bedroom.
As Gomez -- who appeared in Swift's "Bad Blood" music video in 2014 -- dances around the room, there are several posters on the wall that appear to have the "Shake It Off" singer's face on them. On the "niNa!" poster, a girl who looks a whole lot like Swift is wearing sunglasses and looking super cool. There's also a Charlie's Angels poster that appears to have the 27-year-old artist front-and-center. Finally, there's another image that looks to be Gomez's friend wearing '70s-esque aviator sunglasses above the words, "Mandy means mayhem."
The release of Gomez's new music video on Wednesday came less than a week after Swift's frenemy, Katy Perry, released her album, Witness, which includes the song "Swish Swish" that many fans think is about the pop stars' ongoing feud. Just as Perry's album was about to drop, Swift decided it was a good time to put her entire music catalogue back on all the music streaming sites.
