Find out who the guest star is joining Taylor on "Bad Blood!"
The video reportedly features a number of female celebrities, including Zendaya and Hayley Williams who were both spotted on set.
The song already has quite the reputation. It addresses a nasty feud between Swift and Katy Perry, who allegedly hired several dancers of Taylor's - while she was still touring with them. Ouch!
Taylor has also stated she never quite knew where she stood with the Dark Horse singer, friendship wise, until the dancer incident confirmed her suspicions.
UPDATE:Kendrick Lamar was spotted on set! It appears Bad Blood is officially the 4th single from Taylor Swift's monumental album 1989, as the singer was spotted in a dramatic costume today as she headed to and from a film set.
'For years, I was never sure if we were friends or not. She would come up to me at awards shows and say something and walk away, and I would think, "Are we friends, or did she just give me the harshest insult of my life?" Then last year, the other star crossed a line. She did something so horrible, I was like, "Oh, we're just straight-up enemies." And it wasn't even about a guy! It had to do with business. She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me.'The release of Bad Blood marks the first time a standard Taylor Swift diss track has not addressed a man, nor her doomed relationship with one, continuing with Swift's running theme of making her new pop sound and image far less boy-centric than in the past. The video reportedly features samurai swords and kick-boxing - Swift's dramatic dark eye-makeup and hairstyle would certainly suggest this could be true! If Swifty's last three videos are anything to go by, this one is going to be equally as amazing.
