While Taylor Swift has a bevy of best friends in Hollywood, she's certainly got one enemy to deal with. Nothing is sweet between Taylor Swift and the female singer she's dedicated her latest single, "Bad Blood" to. In fact, the country crooner talks about the singer involved but failed to drop a name.

Country crooner Taylor Swift has nabbed another cover for Rolling Stone magazine. The cover photo is daresay a far cry from Swift's look through the years. Taking cues from her best friend Karlie Kloss, Swift looks like a Victoria's Secret model with her wet look which consists of a white tank top and a pair of jeans.

Aside from talking about the "Reinvention" of Taylor Swift, the 24-year old talked about a female singer in the business that has been rubbing her the wrong way. Who would have thought the friendly and sweet Taylor Swift would have an enemy in the biz?

"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!" stated Swift.

"Swifties" will definitely learn more about this female singer once they hear the song "Bad Blood" from her "1989" album.

"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," added the songstress.

Fans are now left to guess who Swift is referring to. For one, there are a number of female singers in the biz that aren't necessarily on good terms with one another. As for Swift, the country crooner is dead set on steering clear of girls who dislike her and she hopes her fans do the same.
