Katy Perry Says She's Down To Work With Taylor Swift If She Apologizes

No big deal or anything, but we might be looking at a Katy Perry-Taylor Swift collaboration.

SAY WUUUUT?!

True story.

KP said she's down to work with Taylor and put all the ~bad blood~ behind her if she apologizes.

The revelation came to light as Katy got grilled on Twitter during a Q&A.

When one asked if she'd ever join forces with the mighty T. Swift, she replied,

If she says sorry, sure!

Confused about why these two are so bitter towards each other? We don't blame you. Their falling out took place years ago now, and no one knows the exact reason why, to be honest.

But fans believe it goes back to an interview Taylor did with Rolling Stone magazine.

In it, she claimed another singer had poached her backing dancers.

People think she was referring to Katy, who warned,

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

Has there ever been a more perfect reference to "Mean Girls"?

She's been subtly throwing shade at Swifty ever since.

When that whole drama kicked off with the Calvin Harris break-up, he tweeted about Taylor and Katy, saying,

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.

Then our good friend KP tweeted this golden Hillary Clinton GIF.

Some would say this is cryptic. Others would brand it a blatant side-swipe at her showbiz enemy.

WE LOVE THE DRAMA, but also, think how awesome a collab would be...
