Kanye West had yet another come-apart Tuesday night (Feb. 23) at a club in L.A., where he was set to debut a an unreleased song from his latest album. The rapper used his time at the mic to launch into a rant in response to Taylor Swift’s Album of the Year Grammy acceptance speech.

West is shown in the video above [Warning: strong language] yelling into the mic and claiming he talked to Swift beforehand about the lyric in “Famous,” which cites his belief that the pair will have sex one day. Swift’s camp denied that interaction happened, revealing that West only asked for the country-pop superstar to promote the song via Twitter, and she declined.

"I called Taylor. I played her — I told her, I said, 'Taylor, I talked to my wife about it,'" West told the audience at the 1Oak. "I said, 'How do you feel about this line, Taylor?' I was like, 'Taylor, I feel like me and you might still have sex.' She said, 'Ooh, Kanye, I like that line.' Then she won her award and said something completely different."

He goes on to shout his disapproval of Swift as a person, shouting: "She not cool no more. She had two seconds to be cool, and she f---ed it up."

West and Swift's beef began with the infamous run-in at the 2009 VMAs, when the rapper interrupted her acceptance speech for an award he believed Beyonce should have won. They made peace a few years later, but the fabric unraveled again after the unveiling of "Famous" during a listening party for West's new The Life of Pablo album.

Swift has not responded. She recently opened the Grammy Awards with a performance of “Out of the Woods” with co-writer Jack Antonoff of the bands Bleachers and Fun. She is currently on a break from music following her hot 1989 tour.
