Taylor Swift’s new song “Bad Blood,” off  her new album“1989,” is about another female artist, but in an interview with Rolling Stone, the singer would not reveal the person’s identity. Swift is known for writing songs about love and relationships (and revenge), but she wanted readers to know this feud had nothing to do with a guy.

"I know people will make it this big girl-fight thing. But I just want people to know it's not about a guy," she explained. "You don't want to shade someone you used to date and make it seem like you hate him, when that's not the case."

It’s someone Swift has known in the industry for some time, but it wasn’t until the female artist stepped over the line that Swift knew where they stood. "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?'" Swift, 24, told the magazine. "[Then last year] she did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy!"

The feud with the unidentified star 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. And I'm surprisingly non-confrontational-- you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it."

Swift has a bevy of famous friends, as noted by Us Weekly. Lorde, Selena Gomez, “Modern Family” star Sarah Hyland, “Girls” star Lena Dunham, Victoria’s Secret model Karlie Kloss, Dianna Agron and Hailee Steinfeld are just some of the singer’s A-list acquaintances.
