The feud appeared to come to an end in 2018, when Swift sent Perry an olive branch in the form of a literal olive branch. Perry accepted the olive branch, and the two singers publicly hugged at the 2019 American Music Awards.
Since then, Swift and Perry have appeared to be on good terms. They have both spoken positively about each other in interviews, and they have even collaborated on a song together. In 2019, they released the song "You Need to Calm Down," which is a message of acceptance and tolerance.
So, are Taylor Swift and Katy Perry friends? It's hard to say for sure. They have both said that they are friendly with each other, but they have not explicitly said that they are friends. It's possible that they are still working on repairing their relationship, or that they are simply content to be cordial with each other.
