We are dissecting the most legendary rivalry of the last decade that divided fan bases and defined pop culture. The Mag Base reveals the silver-edged pages of the "Bad Blood" era between Katy Perry and Taylor Swift.

ACT 1: THE BACKUP DANCER CRISIS (2013)

It all began in 2013 during Taylor Swift’s Red Tour. Three dancers who previously worked for Katy Perry left Taylor’s tour to rejoin Katy’s Prism Tour. Taylor viewed this move as a professional "sabotage."

ACT 2: "BAD BLOOD" AND REGINA GEORGE (2014)

In a Rolling Stone interview, Taylor spoke of an unnamed female artist who "tried to sabotage an entire arena tour." Shortly after, "Bad Blood" was released. Katy fired back with the now-iconic tweet:

"Watch out for the Regina George in sheep's clothing..."

ACT 3: "SWISH SWISH" AND THE PUBLIC APOLOGY (2017)

Katy Perry broke her silence in 2017 with "Swish Swish," widely interpreted as a response to Taylor. However, during her Witness live stream, Katy expressed her desire to end the feud, stating she loves Taylor and wants the best for her.

ACT 4: THE OLIVE BRANCH AND RECONCILIATION (2018-2019)

2018: On the opening night of the Reputation Stadium Tour, Taylor Swift received a literal olive branch and a handwritten note from Katy.

2019: The world watched in shock as the two appeared in the "You Need to Calm Down" music video, dressed as a hamburger and french fries, sharing a hug. The drama was officially over.

Visual: The Great Peace

At The Mag Base, we are thrilled to see this chapter end in friendship. While the feud is over, the cultural impact and the iconic songs it produced remain staples of the pop world in 2026.
