The line in question -- "I feel like me and Taylor might still have sex. Why? Because I made that b**ch famous" -- became a heated he-said/she-said conflict after the album dropped, with West claiming that he asked Swift for permission before recording the song.
However, West’s wife, Kim Kardashian, has previously stated that cameras recorded all of the rapper’s behind-the-scenes process while creating his album, including his phone conversation with Swift. That footage was a topic of conversation on KUWTK, but had never been released, until now.
"I don't really feel like saying much because the Taylor Swift fans love her and I'm all for that," Khloe shared on Sunday’s show. "All I know is I saw the video...I've heard Taylor and I think that Kanye did the right thing."
While the clips she posted don't appear to be the full, unedited conversation, it sounds like that the 1989 singer did indeed approve of her shout-out in the song. West and Swift's conversation was presented in a series of short clips, so it's difficult to discern some portions of their conversation.
In the clips Kim posted, West makes it clear that he cares about his friendship with Swift, and explains that it's out of concern for her feelings that he's asking for her permission. However, West is only seen reading Swift the lyric, "For all my south side n****s that know me best / feel like me and Taylor might still have sex" and not the most contested line, "Why? Because I made that b**ch famous."
"All I give a f**k about is just you, as a person and as a friend. I want things that make you feel good," West told Swift over the phone. "I don’t want to do rap that makes people feel bad… I felt like I just had a responsibility to you as a friend."
Swift can also be heard over the phone sharing her appreciation for West calling her ahead of time, and joking about the controversy the song might spark. Additionally, Swift can be heard saying that she'd tell reporters, when asked, that he called her about the lyrics and that she was OK with them. Which is almost the exact opposite of what ended up going down.
Almost immediately after Kim posted the footage, the hashtag #KimExposedTaylorParty began trending on Twitter as fans and haters alike came out to comment on the controversial clips. Later, Swift commented on the drama in a note posted to her social media accounts, which she captioned, "That moment when Kanye West secretly records your phone call, then Kim posts it on the Internet."
During the show, Kim made it clear why she thinks Swift decided to retract her supposed authorization after the album dropped.
"The camera crew filmed him speaking to Taylor and got their whole conversation. So I think he definitely cared about how she felt," Kim explained. " I think she got freaked out by the reaction and all the sudden she flipped."
However, it was also clear that Kim initially was hesitant about leaking the footage, and didn't want to go to war with Swift.
During the episode, Kim, Khloe and their sister, Kourtney Kardashian, were getting ready to go to a party, and the topic of conversation moved to the tape.
"Why don't you [put it out?]… I'll put it out! What's wrong with you?!" Khloe asked.
"I don't know… why do you even want to get into this battle?" Kourtney responded, serving as a voice of reason among the sisters.
"I just wanted to like, kind of stay out of it," Kim replied. "I don't want any of us to get involved."
Clearly, the 35-year-old reality star had a change of heart in the interceding months.
