Katy Perry just opened up about her FEUD with Tay Tay on Twitter

Is Katy Perry making the first move?

It looks like the singer is about to let go of her grudge with Taylor Swift.

The pair have been on/off feuding for years now, but when someone asked her on Twitter if she'll ever see them working together, Katy's reply surprised everyone.

Twitter user Camille asked, "will you collab with Taylor Swift?" to which Katy replied, "if she says sorry, sure!"

We're glad she didn't ignore the question, or write a big fat NO, because let's be honest, these two superstars making music together would be awesome.

And you never know… Taylor is back in the studio working on her next album…
