Kanye West Busts Taylor Swift with Secret Recording ... She Calls 'Famous' a 'Compliment' (Updated Video)

Kim Kardashian just unloaded on Taylor Swift, posting audio of a conversation Kanye West secretly recorded in which he reads some of the lyrics of "Famous" to Taylor -- in particular having sex with her -- and she calls it a "compliment."

As you know Taylor went ballistic after Kanye said he got her approval to record the lyrics in the song. She says she never gave permission and called it "misogynistic."

But the tape says otherwise. Our sources say Taylor has threatened Kanye over releasing the tape, claiming it's illegal. But the Kardashians decided to put it out there.

One thing in Taylor's favor. We've learned at no point in the conversation did Kanye say to Taylor he would refer to her as "bitch." As you know, in the song, he says, "I made that bitch famous."

9:30 PM PT -- Taylor is pissed. She says Kim and Kanye are committing "character assassination," because they're making it seem like she lied when -- as we reported -- the truth is Kanye NEVER mentioned the "that bitch" line.

Taylor posted a scathing message ... "You don't get to control someone's emotional response to being called "that bitch" in front of the entire world."
