Katy Perry revealed on Twitter that she's waiting for an apology from Taylor Swift after a fan asked Perry if she'd record a song with the 1989 singer.

When asked by HerWonkEye if she would collaborate with Swift, Perry replied: “If she says sorry, sure!”

The alleged feud between the two singers started around 2014 when Swift released the song “Bad Blood.” Although the quarrel has never been confirmed, Swift referenced it in an interview.

“For years, I was never sure if we were friends or not,” the “Wildest Dreams” singer told Rolling Stone in September 2014. “She would come up to me at awards 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?”

It looks like Perry is ready to put the beef aside. The question is: will Taylor apologize?
