We never thought we'd see the day!

Katy Perry sent an actual olive branch and an apology letter to frenemy Taylor Swift yesterday, in an attempt to squash their years long feud, and it seems to have worked!

"I just got to my dressing room and found this actual olive branch. This means so much to me," T-Swizz said on her Instagram stories while showing off the sweet gesture.

We got a peek at KP's note, too!

"Hey Old Friend — I’ve been doing some reflecting on past miscommunications and hurt feelings between us," part of it reads, along with her being "deeply sorry" and wanting to "clear the air."

The beef between the two began when TS accused the "Roar" songstress of attempting to sabotage her tour by stealing her backup dancers. Since then, they've made diss songs about each other, taken turns calling each other Regina George from Mean Girls, and avoided awkward award show run-ins. Now, all can be forgotten!

The California girl confessed that she was ready to put their bad blood - pun intended! - behind them during an interview with The Thrive Global Podcast last summer.

"I am ready to let it go. I forgive her and I’m sorry for anything I ever did, and I hope the same from her … I love her, and I want the best for her. And I think she’s a fantastic songwriter," she explained.

"Maybe I don’t agree with everything she does and she doesn’t agree with everything I do, but I just really, truly want to come together in a place of love and forgiveness and understanding and compassion,” she added.

Perhaps this is giving Kimmy K some bright ideas?
