Taylor Swift, 2014

The Taylor Swift Lyric Guessing Game can officially begin.

The country pop superstar covers the new issue of Rolling Stone, and in the long profile -- which you can read in full online -- Swift announces that while there won’t be many calling-out-the-boys tracks on her upcoming 1989 album (she shared that she hasn't been on a date since breaking up with One Direction's Harry Styles in January 2013), there is a song called "Bad Blood" about a friendship gone south.

According to the magazine, Swift has this to say about the unidentified female celebrity: "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!"

Swift further explained: "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. 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."

Since we don’t yet have Swift's secret-message liner notes to turn to for extra intel, we'll just have to freely speculate about who would dare be a frenemy to America’s BFF.

1. Katy Perry
The Prism singer seems the most likely candidate -- and indeed, Internet detectives are already pointing to the fact that some dancers left Swift's Red Tour in 2013 to go back to dance for Katy on her Prismatic Tour. Additionally, while Swift notes this fallout isn't over a guy, the fact that the two both dated John Mayer probably doesn't help the relationship.

2. Demi Lovato
There isn't a whole lot of information out there about Lovato's relationship with Swift, save for the fact that they (alongside Selena Gomez) used to regularly hang out all the time, and these days? (Publicly) not so much. And then there's this quote from Lovato from last year: "A lot of celebrities don't open up to their fans, they just tell them what they want to hear. They don't really tell them things that can benefit their lives, they just, you know, maybe flaunt around a boyfriend and sell a couple of albums." Not so much a backhanded compliment as a straight-up insult.

3. Miley Cyrus
It was just five years ago Swift and Cyrus teamed up to perform "Fifteen" at the 2009 Grammys, but the tabloids have pitted the two stars against each other before for their different styles and performances. Just dumb gossip or is there some truth that the two aren't exactly each other's biggest fans?

4. Selena Gomez
Fans have wondered how close the onetime inseperrable BFFs are recently, particularly with Gomez possibly getting back together with walking bad idea Justin Bieber, a relationship with which Swift couldn't hide her open disgust. But who among us hasn't at one point or another disliked a friend's boyfriend? Despite the sometimes-speculation, it's clear the two are still close. In the RS profile, Swift jokes about getting Selena to move to NYC with her.
Odds: 50-1, or About As Likely As Taylor Swift Getting Back Together With Harry Styles.

5. Karlie Kloss
Just kidding. Fans learned in the profile that not only is the Victoria's Secret model one of Swift's best friends, she's practically her roommate, with a room in Swift's New York City apartment dedicated just for her use.
