The Red World Tour of Taylor Swift was sabotage by a fellow female singer; this is according to Swift's revelation. The 24 year old Grammy winner says, the female singer did a horrific act by trying to pay some of her production staff to go against her.

In a Rolling Stone interview with Swift, she stated: ''She did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy! 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.''

The singer has bashed the mystery female singer in her new song, Bad Blood, which is part of her album, 1989.

She claimed: ''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? For years, I was never sure if we were friends or not."

The world of Twitter has gone crazy in following Swift's comments and fired out speculations that the singer could be talking about Katy Perry, after the unmane person on the social media site, referenced Perry as Regina George, as the lead character in the film Mean Girls.

Swift twitted: ''Watch out for the Regina George in sheep's clothing...''

She also clarified, ''But I just want people to know it's not about a guy. 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. And I knew people would immediately be going in one direction.''
