Katy Perry ends Taylor Swift feud by sending her telling gift on opening night of Reputation Stadium Tour

'Cause, baby, now they don't have bad blood! 

Katy Perry seemingly ended her feud with Taylor Swift after years of back-and-forth on Tuesday by sending the "Blank Space" singer a gift on the opening night of her Reputation Stadium Tour.

Swift revealed the gift on her Instagram Story on Tuesday afternoon before she took the stage in Glendale, Arizona, which was a literal olive branch in a white box along with a handwritten note that started, "Hey Old Friend." On brand for Perry, the envelope was sealed with a golden retriever puppy sticker.

"So, I just got to my dressing room and found this actual olive branch," Swift said in the video. "This means so much to me."

Swift and Perry's feud was first revealed in an infamous Rolling Stone cover story about Swift, in which she revealed that her song "Bad Blood" was written about an unnamed singer who "tried to sabotage" her latest tour. Fans pointed to two of Swift's dancers leaving her Red tour to join Perry's Prism tour as the truth behind the so-called sabotage.

After the release of the interview, Perry tweeted, "Watch out for the Regina George in sheep's clothing," alluding to Swift.

In the nearly four years since, Perry and Swift had thrown jabs at one another publicly, both overt and subliminal, but it appears as though those are officially over with. Water under the bridge!
