Taylor Swift vs. Katy Perry (2014-2019)
It may have started earlier, when Katy started getting close to John Mayer, her former friend Taylor's ex, but it really started in 2014 when Taylor released the blind item disguised as a song, "Bad Blood." She told Rolling Stone that the song was about "another female pop star" that tried to sabotage her arena tour. Turns out the crime Katy was guilty of was trying to hire some back up dancers that Taylor was using on her tour for her own tour. After a bunch of petty trolling back and forth, in 2016 Perry named her latest perfume "Mad Love," a reference to the lyrics of "Bad Blood."
In 2017 when Perry was promoting her new album Witness on Carpool Karaoke she explained the start of the feud to James Corden and said that Taylor started it, "and she needs to finish it." When Perry released Witness at midnight on June 10th, Swift made her entire back catalogue of music available on Spotify at the exact same moment after a years-long battle with the streaming service. Swift pulled a similar stunt that August, releasing the lyric video for her song "Look What You Made Me Do" on the same day that Perry released the video for her diss track "Swish Swish," which featured Nicki Minaj, another artist Swift had beef with.
By 2018 things were on the mend though. Perry, never one for subtlety, mailed Swift an actual olive branch and a letter of apology, which Swift posted on social media. Swift then sent Perry a plate of cookies on a plate that said, "Peace at last." Perry, doing her duty as a global citizen in the internet age, posted them on Instagram. While that is considered the end of the feud, it was cemented this year when Perry appeared in Swift's video for her song "You Need to Calm Down." While things are calm now, we are going to miss the grand scale cattiness that this brought us for so many years.
