The day Harry Styles cut his hair off, the day Little Mix formed and now. the day Katy Perry and Taylor Swift finally kissed and made up. "This means so much to me", Swift says in the video, which is captioned "Thank you Katy" with a heart emoji.
Katy Perry, 33, had employed the group of dancers originally on her California Dreams tour and later Taylor took them on for her Red tour.
An olive branch is a traditional symbol of peace. See the best reactions below.
An attempt by Perry a year ago to bury the hatchet, when she apologized for past actions and called Swift a "fantastic singer", was met with silence from Swift.More news: Day wins at Wells Fargo Championship
Perry also appears to write she is "deeply sorry" over "past miscommunications". Believe it or not, on the opening night of Taylor Swift's "Reputation Tour", K-Pez shipped a surprise package to the "Bad Blood" star with a personalised note too! Perhaps she was thinking of Taylor? "Honestly, it's really like, she started it and it's time for her to finish it".
"Well, there's a situation [between me and Swift]", Perry said at the time. "I really want to clear the air..." before it's covered.
Less than a month later, Perry said she was "ready to let it go", during an interview with Arianna Huffington's Thrive Global Podcast.
"She would come up to me at awards shows 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?' [Then] she did something so terrible".
