Taylor Swift Won’t Say Sorry To Katy Perry: No Chance For Collab Between The Two Pop Stars

"Roar" singer Katy Perry's openness to collaborate with "Style" singer Taylor Swift has just been shut by the "Love Story" singer. Taylor Swift is not sparing anyone from her rage.

Katy Perry's answer to a fan's tweet asking if she would work with Taylor Swift was: "if she says sorry, sure!" It looks like the "Back to December" singer is closing her doors to Orlando Bloom's present love interest, Katy Perry.

Apparently, they are not of the same level, as Katy Perry's song were not as popular as those of Taylor Swift. "Why would Taylor want to collaborate with someone whose latest single, 'Rise,' didn't even break the Top 10?" a source told Hollywood Life. The source even pointed out that Taylor Swift is a 10-time Grammy winner while Katy Perry has none.

The beef between the two dates back to 2014, the Huffington Post reported. The blonde singer told an interview with Rolling Stone that her song "Bad Blood" was a female pop star who "tried to sabotage an entire arena tour."

As Swiftees would know it, the "Blank Space" singer writes songs about almost everything. That's why with "Bad Blood," she said she was just venting her emotions in songwriting. "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?'" Taylor Swift said to the Rolling Stone in 2014.

Fans and non-fans alike were sure it was the "Dark Horse" singer after she posted on Twitter: "Watch out for the Regina George in sheep's clothing," just after the interview with Taylor Swift. Calvin Harris, ex of Taylor Swift, even confirmed this recently when he tweeted: "I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry. I won't allow it."
