Their feud, which seemed to be resolved, stemmed from Kardashian defending her then-husband Ye, formerly known as Kanye West, when he called Swift "That bitch" in his 2016 song "Famous."

Ye and Kardashian said Swift gave her blessing to the song. Kardashian tried to prove this by publicly sharing short clips of a phone conversation between Ye and Swift about "Famous" before its release. Ye never mentions the notorious "I made that bitch famous" line in the clips. Swift didn't dispute the validity of the clip, but said she never gave permission for the "bitch" lyric.

It was a huge pop culture moment, as three of the most influential people of the 2010s clashed. Swift bounced back from the drama with her 2017 album "Reputation," and her popularity skyrocketed. Although Swift was already a rising star at the time, her global domination only began after her "Reputation" era and beefing with Kardashian.

In "ThanK you aIMee," Swift never mentions Kardashian by name, but it's easy to see why fans are speculating. For starters, "K," "I," and "M" are capitalized in the song title, which spells "Kim."

Here's what to know about Kardashian and Swift's feud and every lyric that references it.

In recent years, Kardashian seemed ready to move on from the drama.

The "Famous" feud reignited in 2020 when the full phone call between Ye and Swift leaked online. Swift's fans felt vindicated because the call showed that the "bitch" lyric was never mentioned during the call. However, Kardashian tweeted after the video leaked that she never lied about the call or the "bitch" lyric.

Since then, the drama has subsided, and Kardashian has started praising Swift, apparently keen to move on from the feud.

Swift, on the other hand, has not moved on.

In December 2023, Swift addressed the drama in her Time Person of the Year profile, saying it felt like "a career death."

"You have a fully manufactured frame job, in an illegally recorded phone call, which Kim Kardashian edited and then put out to say to everyone that I was a liar," she said. "That took me down psychologically to a place I've never been before. I moved to a foreign country. I didn't leave a rental house for a year. I was afraid to get on phone calls. I pushed away most people in my life because I didn't trust anyone anymore. I went down really, really hard."

This appears to be the first time Swift has written about Kardashian

Swift took aim at Ye during her 2017 "Reputation" era by releasing multiple songs that seemingly reference their feud. Kardashian didn't get caught in the crosshairs in that album, but fans have speculated that Swift referenced Kardashian's relationship with Ye in her 2020 song "Mad Woman" and 2022 song "Vigilante Shit."

However, "ThanK you aIMee" appears to be the mostblatant reference to Kardashian. Swift sings about a school bully called "Aimee" who made her stronger, who fans think is Kardashian.

Fans have speculated that lyrics including "bronze spray-tanned statue of you" and "your words are still just ringing in my head" refer to Kardashian's physique and the infamous phone call.

Swift also seems to nod to the idea that "Aimee" is a fake name: "And so I changed your name, and any real defining clues / And one day, your kid comes home singin' / A song that only us two is gonna know is about you."

In response to these lyrics, fans on Twitter were quick to reshare the 2023 video of Kardashian and her daughter, North West, dancing to Swift's "Shake It Off" song on their joint TikTok account.

In the song, Swift also implies that her mother, "a saintly woman," wished death on Aimee.

Representatives for Kardashian and Swift did not immediately respond to a comment request from Business Insider.
