Katy Perry was on Car Pool Karaoke with James Corden and she reveals what her beef with Taylor Swift was about.

“It’s true. There’s a situation,” Perry said. “Honestly, it’s really like she started it, and it’s time for her to finish it.”

Katy said it all started over her backup dancers going to work on Taylor’s tour which she gave her blessing.  But when Katy was ready to go back on tour, the dancers approached Taylor’s tour management about going back on tour with Perry.  That was when the dancers were then fired.  Katy tried to reach out to Taylor directly about the situation but never received a response.

“I tried to talk to her about it, and she wouldn’t speak to me,” Perry said. “I do the right thing any time that it feels like a fumble. It was a full shutdown, and then she writes a song about me, and I’m like, okay, cool, cool, cool, that’s how you want to deal with it? Karma!”

Looks like Katy wants to once and for all squash it.

“What I want to say is that I’m ready for that B.S. to be done,” she said. “Now, there is the law of cause and effect. You do something, there’s going to be a reaction, and trust me, daddy, there’s going to be a reaction.”
