There have been rumors that Tay's song is so about Katy and their not-so-friendly encounters in the business. That might be the case, but T-Swift definitely didn't sign her on for the gig. Instead, Haylee Williams, Zendaya and Cara Delevingne were spotted taping the video with Tay.
The ladies were photographed at a studio in Los Angeles in white robes, with futuristic-looking hair and cat-eye makeup. We have no clue what the video is going to be about, but we're pretty sure it's going to be epic. We think it'll be REALLY hard to beat the "Blank Space" video, though.
All of this "Bad Blood" drama began when Taylor told Rolling Stone that the single is about another female musician who went from frenemy to "straight-up enemy" after stealing dancers from her tour. Katy then fired back with a Mean Girls reference tweet.
