Taylor Swift has revealed her new album 1989 features a scathing song about another female artist-turned-frenemy, with some reports suggesting it's about Katy Perry!

In a revealing new interview with Rolling Stone, Swift tells the writer that a tunetitled Bad Blood — which the mag describes as the “angriest” on her new LP— is a collection of all of the shelved mental burns she thought of but never managed to lob at a certain fellow female musician.

The 24-year old went on to recall a moment last year, stating: "She did something so horrible. I was like, ‘Oh, we’re just straight-up enemies'."

What’s more, Swift recounted that their beef wasn’t even about a boy — just business. And it was one feud she just couldn’t shake off.

Taylor said the woman, whom she declined to identify, “tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me."

Despite rumours suggesting K-Pez is the target of the track, Taylor concluded: "I know people are going to obsess over who it’s about, because they think they have all my relationships mapped out.

"My intent was not to create some gossip-fest. I wanted people to apply it to a situation where they felt betrayed in their own lives.”

Buzzfeed has since fuelled reports that Bad Blood is about Perry, revealing that three of Swift's back-up dancers left half-way through her Red tour to work with Katy.

Swift is also said to have poked fun at claims Perry stoleSara Bareilles' song Brave for her track Roar, inviting Sara on stage to sing the song, calling it "so original".

And despite Taylor insisting her beef with the mystery female wasn't about a man, the pair have both dated John Mayer!

Katy is yet to respond to the rumours. Watch this space...
