Female relationships can be really difficult and Taylor Swift usually manages to stay above the fray. The singer is known for being a real girl's girl and takes a lot of pride in the fact that she has so many strong female friendships. Of course, that doesn't mean that all of the high school type drama that catty women can cause hasn't affected the young star.

We're so used to her writing songs about failed romantic relationships that it's almost shocking to learn that the new song "Bad Blood" off of Taylor's upcoming 1989 release is actually about a female enemy, according to Rolling Stone.

In a new interview out in the latest issue of RS, Taylor talks about the situation with another competing singer saying,

"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] she did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy!"

The situation took a really serious turn when Swift realized that this chick was actually trying to sabotage her arena tour by hiring people right out from beneath her! This wasn't just a little pissing match that these two were involved in but total attempted career tampering took place and as a result Taylor now refuses to speak to the still-unnamed, sworn enemy.

Can you guys believe the lengths that some will go to in order to get ahead of their competition in Hollywood? While Taylor Swift is refusing to throw direct shade by naming names, who do you think "Bad Blood" is really about? Tell us in the comments below!

1989 is scheduled to drop this coming Oct. 27 via Big Machine Records.
