Katy Perry Says She'll End Her Feud With Taylor Swift - There's Just One Tiny Condition
Katy Perry has said she will put an end to her long running feud with Taylor Swift and possibly even work with her - if she apologises.
The pop princesses famously fell out in 2012 after Katy allegedly pinched Taylor's backing dancers from her tour.
But in a Q&A on Twitter, Katy offered an olive branch to her former friend and even suggested they could work together in future.
But there is one condition. And it's a biggie.
The Dark Horse singer said, when asked if she would ever work with Taylor: "If she says sorry, sure."
Their row, which reportedly started over three backing dancers, was recently highlighted again when Taylor's ex Calvin Harris waded in.
He said in a series of tweets: "Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though.
"I figure if you're happy in your new relationship you should focus on that instead of trying to tear your ex bf down for something to do
"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."
So could they collaborate? Or has there just been too much Bad Blood between them?
