Writing and composition.
Swift wrote "Bad Blood" about an undisclosed female artist. She says that the artist attempted to sabotage one of her concert tours by hiring people that worked for her (Swift). There are rumors from "Rolling Stone", "Billboard", "Time" and "Washington Post" that singer-songwriter Katy Perry is the subject of the song. The original album version of "Bad Blood" only has Swift singing.

Critical reception.
The original album version of "Bad Blood" received mixed reviews from music critics. But, the remixed version of the song received mostly positive reviews. Much of the praise was for Lamar's guest verses and the reworked instrumental. George Seabrook, writing for "The Edge" in Southampton, England, gave the song four-and-a-half stars out of five. He praised the song for "Lamar’s simple, brutally effective verses". He also said that Swift and Lamar made "not just one more meaningless stunt collaboration, but a powerful new duo".
