Leaked footage appears to show an unedited version of the infamous phone conversation that took place between Taylor Swift and Kanye West over the rapper’s song “Famous“.

In 2016, West’s wife Kim Kardashian shared a clip that showed Swift approving a lyric in which West raps: “I feel like me and Taylor might still have sex.”

Kardashian claimed the clip proved Swift was a “snake” because the pop star said she had not been informed that West would call her a “bitch” in the song.

The incident caused a widespread backlash against Swift and is believed to be partly responsible for her hiatus from the music industry.

In the previously unseen footage that is being shared on Twitter, West is shown in a 25-minute conversation telling Swift about the song, explaining when he wants to release it and his hope that Swift would tweet it.

“It has a very controversial line at the beginning of the song about you,” West tells her, adding: “I don’t think it’s mean.”

West then delays telling Swift the lyric, explaining: “It says, uh... and the funny thing, when I first played it and my wife heard it, she was like, ‘Huh? What, that’s too crazy,’ and then when Ninja from Die Atwoord hear it, he was like, ‘Oh my god, this is the craziest s**t, this is why I love Kanye...’ and now, it’s like my wife’s favourite f***ing line... I just wanted to give you some premise of that.”

He then says the lyric: “To all my Southside n***as that know me best / I feel like Taylor Swift might owe me sex.”

Swift is heard laughing before she says: “That’s not mean.”

“OK, well this is the thing why I’m calling you, because you got an army, you own a country of motherf***ing 2bn people, basically,” West says. “If you felt that it’s funny and cool and hip hop, and felt like it’s the College Dropout and Ye that you love, people would be way into it, and that’s why I think it’s super genius to have you be the one that says, ‘Oh I like this song a lot... this is cool.’”

“I need to think about it,” Swift tells him. “When you hear something for the first time you need to think about it, because it is absolutely crazy-”

The track itself is a dreamy, lush soundscape filled with breathless sighs and dramatic pauses that recall Swift’s fellow old Hollywood obsessive, Lana Del Rey. Kevin Winter/Getty Images Taylor Swift's 20 best songs 19) “Paper Rings” A pop-punk song! Swift is at her most energetic on a song that has more than a hint of Toni Basil’s “Mickey”, from the hand-clapping beat to the distorted scuzz added to her vocals. Taylor Swift's 20 best songs 18) “Style” Until “Dress” appeared on Reputation, “Style” was Swift’s most bold and sensuous song, driven by a pulsing beat and an urgent electric guitar riff. It plays on the idea that it’s easy to leave someone but a lot harder to stay away, especially if your lover has that “James Dean daydream look in [their] eye”. Vevo Taylor Swift's 20 best songs 17) “Back to December” This was a first for Swift, who apologises to an ex who treated her perfectly, while she perhaps didn’t value the relationship as much. It’s a noteworthy song simply to point out that Swift, who has faced multiple accusations of “using” her relationships to drag her ex-boyfriends, is more than capable of self-criticism. Vevo Taylor Swift's 20 best songs 16) “Love Story” A Swift classic about star-crossed lovers, inspired by (what else?) Romeo and Juliet. This is a country pop song is a prime example of Swift’s skill as a story teller – one who understands the power of a forbidden romance. Vevo Taylor Swift's 20 best songs 15) “Out of the Woods” Swift emulates Bruce Springsteen on this Eighties synth-pop “get in the car and go” epic, which lasts not a second too long and ends so abruptly that it leaves you gasping to catch your breath.

There’s so much more bite on this track than “Blank Space”, despite the similar themes – here she is merciless upon learning a man has used her name, or spent her money, behind her back.

Dia Dipasupil/Getty Images for ABA Taylor Swift's 20 best songs 12) “Tim McGraw” There’s something very moving about Swift opening her first album with a song that intertwines the old and the new. Nashville is notoriously unkind to female country artists, particularly young ones, so you can’t help but admire a then-16-year-old Swift, who offered a profound respect to one of her biggest inspirations on her debut single. Vevo Taylor Swift's 20 best songs 11) “Dress” This song is essentially one big, lustful sigh: Swift seems to delight in a secret romance where she “only bought this dress so you could take it off” and quite literally pants with anticipation. Getty Images for TAS Taylor Swift's 20 best songs 10) “Miss Americana & the Heartbreak Prince” At first, you could mistake this for a love song. It is, in a way - Swift's most political song to date addresses her heartbreak over America as she witnesses it in turmoil. She takes classic themes from her earliest work - white knights, red roses, princesses and high-school prom - and spins all of it into a metaphor for a perceived loss of innocence following the 2016 general election. Add the subliminal cheerleader chant - "GO! FIGHT! Win!", and this makes for one of Swift's best songs of her career. Getty Taylor Swift's 20 best songs 9) “We Are Never Ever Getting Back Together” While Red signalled Swift’s full-blown transition into pop music, she couldn’t resist putting the odd country twang on songs such as “We Are Never Ever Getting Back Together”, which mocks an ex for being snobbish about his “indie record label that’s much cooler than mine”. The most spectacular is really the beginning of the song, where she delivers an astounded “what?” upon being told the guy needs space: “We hadn’t seen each other in a month.” Taylor Swift's 20 best songs 8) “Dear John” John Mayer lashed out over this song in 2012, clearly upset after Swift alluded that it was about their past relationship. He called it “cheap songwriting” in reference to using their personal lives for material – whatever you think of that, it’s features of her best vocal performances and brilliant songwriting – right down to the Mayer-ism of that wavering electric guitar line. Then there are the lyrics themselves: “You are an expert at sorry/ And keeping lines blurry/ And never impressed by me acing your tests/ All the girls that you’ve run dry/ Have tired, lifeless eyes/ ’Cause you burned them out.” Medic!

Her skittishness on “Delicate”, about the danger of rushing into something, of sharing too much of yourself too soon with someone you’re still getting to know, is all too palpable as the beat switches up like a nervous heart.

The song appears on Reputation, released after Swift’s lengthy hiatus from the spotlight, and its lyrics speak of a person blissfully content in her relationship – to the point that the outside world is just white noise. It includes some of her finest lyrics, too, with superb references to those castles of old crumbling “overnight” and nods to her Anglophilia (“my baby’s fit like a daydream”). Getty Images Taylor Swift's 20 best songs 5) “Our Song” “Mean” is beaten only by “Our Song” as Swift’s most “country” release, helped a lot by her endearing portrait of “the slam of screen doors” and driving along country lanes listening to the radio. Swift is a master of the meta-narrative, so her making a song about a song based on sounds from real-life is all kinds of perfect.

"I’m the one who burned us down/ But it’s not what I meant/ Sorry that I hurt you.” Taylor Swift's 20 best songs 1) “All Too Well” Swift’s mastery of storytelling has never been better than on this, a standout song not just from Red, but of her career to date. It’s the slow-build from those bittersweet memories of “dancing in the refrigerator light” to a devastating, stadium-sized anthem that leads to her delivering arguably her best-ever line – with one of her best vocal performances: “You call me up again just to break me like a promise/ So casually cruel in the name of being honest.” Rex

The clip then cuts off. In a separate clip that is being circulated on Twitter, apparently from the same call, Swift is heard telling West: “I [sold] a full 7m of that album before you did that, which is what happened.”

Her comment appears to be in reference to Fearless and West’s notorious stage-crash while Swift was being honoured for Video of the Year at the AMAs.

At no time in the clips does West make any mention of the fact that he would call Swift a “bitch” in the song or claim he “made her famous”.

At the time of writing, neither Swift nor West have publicly commented about the new video. #KanyeWestisOverParty was one of the top trends on Twitter, similar to the 2016 #TaylorSwiftisOverParty trend sparked after Kardashian shared the edited video.
