A guide to everyone Taylor Swift sings about in 'Tortured Poets Department' -- and their reactions

Taylor Swift didn't hold back on calling everyone out on her newest album, "The Tortured Poets Department," and the reactions are rolling in.

The surprise double album was released in two parts on April 19, giving exuberant Swifties plenty of material to analyze — including multiple celebrity call-outs.

Kim Kardashian

Swift and Kardashian have a long-standing feud, which started with Swift and Ye back in the day and goes back to Kimye's infamous doctored phone call, which appeared to prove Taylor had given consent for a nude wax figure of her to appear in Kanye's "Famous" music video. TLDR: The call was edited, but Swift was ripped to shreds online anyway, an experience that inspired her now legendary "Reputation" album.

Swift isn't quite letting Kardashian off the hook, and "TTPD's" "thanK you aIMee" pointedly had the letters of Kardashian's first name capitalized in the title.

"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," Taylor wrote, apparently referencing daughter North West's TikToks that have featured her songs in the past.

Kardashian didn't respond directly to the taunt, but she did post a throwback photo with Swift's ex-best friend Karlie Kloss on mutual pal Derek Blasberg's birthday. Whether it was a coincidence is anyone's guess.

Matty Healy

The 1975 frontman was the surprise "TTPD" guest star. He and the "Bejeweled" singer appeared to have had a short fling following her split from Joe Alwyn, but the lyrics in "TTPD" have led to speculation that the two were involved for far longer.

The title track is particularly damning: "You left your typewriter at my apartment," Swift sings, referencing Healy's apparent penchant for the old-school device. ("Who uses typewriters anyway?" she later asks.)
