Apparently, all you need to do to end a years-long feud with Katy Perry is apologize to her.

On Saturday, the 31-year-old singer decided to answer some of her fans' questions on social media while waiting for a food delivery. When one fan on Twitter asked if she would be collaborating with Taylor Swift, Perry wrote back, "If she says sorry, sure!

In case anyone forgot, Perry and Swift were quite friendly until 2014 — when Perry allegedly tried to "sabotage"Swift's tour by stealing her backup dancers, Swift said in an interview withRolling Stone.Then in 2015, Swift put out "Bad Blood," which many fans speculated was about her feud with Perry.And of course, who could forget Calvin Harris' now-deleted Twitter rant, in which he accused Swift of looking for "someone new to try and bury like Katy"?

Now, it looks like Perry is willing to extend an olive branch to her former pal if she apologizes for their beef. Swift has yet to respond — but between her recent breakup with Tom Hiddleston and her never-ending drama with Kanye West and Kim Kardashian, we're thinking Swift should take this opportunity to make amends with Perry and come out with a new hit song in the process.
