I think I’m going to hang her poster on my wall now.

“Perry responded, “You’re as sweet as pie!
Let’s write a song together about the subject we know best… for my new record.
It’ll be brilliant.”

(The proposed collaboration never happened.)
But by the time 2014 rolled around, things changed.
She added, “And it wasn’t even about a guy!

It had to do with business.
She basically tried to sabotage an entire arena tour.
She tried to hire a bunch of people out from under me.

And I’m surprisingly non-confrontationalyou would not believe how much I hate conflict.
So, now I have to avoid her.
It’s awkward, and I don’t like it.”

It’s not going to happen.”
She went on to add that it was natural that she has “enemies.”
“It’s not real if someone appears to never have any issues with anyone,” she explained.

“I have my friends.
I have enemies.”

I just needed to divert them away from the easiest target.
Listen to the song.
It doesn’t point to any one person or any one situation.

And nothing could be further from the truth.
In a series of now-deleted tweets, Harris seemed to address the timing of the reveal.
(At the time, Swift was dating actorTom Hiddleston.)

Harris then name-dropped Perry.
I won’t allow it,” he wrote.

I made that bitch famous."
It’s not about that.
End of story."

“We got to keep it real, honey.
This record is not about anyone else!
This record is about me being seen and heard so that I can see and hear everyone else!

It’s not even about me!
It’s about everything that I see out there that I digest.
I think there’s a healing in it for me and vulnerability.

That’s not new.

They said, ‘Okay, well we’re gonna go and talk to management about it.’
And they did, and they got fired.”
Perry claimed Swift never talked to her about the dancers despite her attempts.
“Now, there is the law of cause and effect.
It’s all about karma, right?…
Perry answered: “100 percent.”
Especially when someone tries to assassinate my character with little girls [her fans].
That’s so messed up!”
She also acknowledged that her longtime collaboratorMax Martinco-produced and co-wrote Swift’s “Bad Blood.”
I’m not supposed to tell him what he can and can’t do,” she continued.
Just like you do you, make your own choices…
I’m not his mother.”
“I just got back to my dressing room and found this actual olive branch.
This…means so much to me,” she said in a video posted to her Insta story.
Safe to say, Perry was no longer chained to the rhythm of the bad blood with Swift.
Guess they “learned a lesson that stressin' and obsessin' about somebody else is no fun.”
September 2019
Both of the entertainers talked about their rekindled friendship in separate interviews.
Perry first went onThe Ellen DeGeneres Showandtold the audiencethat “it was actually just a misunderstanding.”
Scorpios just strike when they feel threatened.'
And I was like, ‘Well, I’m an archer.
Imagine being sung to sleep by Katy Perry while wrapped in a handmade blanket from Taylor Swift.
A perfect world does exist.
