To recap: a song on Kanye's album The Life of Pablo contains the lyrics: "I feel like me and Taylor might still have sex. Why? I made that b*tch famous." That's a reference to when Kanye crashed Taylor's acceptance speech at the MTV Video Music Awards 2009 to proclaim Beyonce should have won instead.
Kanye, 39, claimed he phoned Taylor, 26, and had her blessing to release the track, but Taylor's reps denied this, saying Kanye had called Taylor to ask her to put the song on her Twitter, rather than telling her what the lyrics were.
And then Taylor took a swipe at Kanye in her Grammys acceptance speech this year, when she spoke about others taking the credit for her fame and success.
But in a new interview with GQ magazine, Kim alleges that Taylor was aware of the lyrics and the couple can prove that because the phone conversation was caught on video.
Kim, 35, told the mag: "She totally approved that. She totally knew that that was coming out. She wanted to all of a sudden act like she didn't. I swear, my husband gets so much sh*t for things [when] he really was doing proper protocol and even called to get it approved.
"It was funny because [on the call with Kanye, Taylor] said, 'When I get on the Grammy red carpet, all the media is going to think that I'm so against this, and I'll just laugh and say, 'The joke's on you, guys. I was in on it the whole time.'And I'm like, wait, but [in] your Grammy speech, you completely dissed my husband just to play the victim again."
Taylor, however, is disputing this.
A statement from Taylor's team released to GQ threw shade at Kimye, and reiterated that although Taylor and Kanye had spoken on the phone, she did not hear 'Famous' until it was released to the public.
"Taylor does not hold anything against Kim Kardashian as she recognises the pressure Kim must be under and that she is only repeating what she has been told by Kanye West," said Taylor's rep.
The spokesperson went on to say "much of what Kim is saying is incorrect", claiming the phone call happened in January 2016 and Kanye had asked Taylor to release 'Famous' on her Twitter account (which she didn't), but did not tell her the nature of the lyrics.
"A song cannot be approved if it was never heard," said the statement.
"Kanye West never played the song for Taylor Swift. Taylor heard it for the first time when everyone else did and was humiliated. Kim Kardashian's claim that Taylor and her team were aware of being recorded is not true, and Taylor cannot understand why Kanye West, and now Kim Kardashian, will not just leave her alone."
Over to you, Kim and Kanye...
