Guess what? Now she's beefing with none other than Kim Kardashian. WE KNOW.
Remember when Kanye West released his song Famous, in which he raps the line, "I feel like me and Taylor might still have sex. Why? I made that bitch famous", and the world, including Taylor, was outraged?
Kanye then went on to defend his lyric by insisting the Shake It Off singer had approved it before the song was released, which Taylor flat out denied during her Grammy acceptance speech earlier this year.
But now, Kanye's wife is supporting her man in her latest interview with GQ, where the reality star insists that Taylor approved of the song.
"She totally approved that. She totally knew that that was coming out," claimed Kim.
"She wanted to all of a sudden act like she didn't. I swear, my husband gets so much shit for things [when] he really was doing proper protocol and even called to get it approved."
The Keeping Up With The Kardashians star later explains that there were other people who heard the conversation – and she even has video evidence of the phone call in which Taylor apparently joked: "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'."
Kim also alleged that Taylor's attorney sent a letter to ask the power couple not to do anything with the footage.
However, a spokesperson for Taylor has since said: "Taylor does not hold anything against Kim Kardashian as she recognizes the pressure Kim must be under and that she is only repeating what she has been told by Kanye West.
"However, that does not change the fact that much of what Kim is saying is incorrect."
Sheesh. What do you make of it? Let us know by tweeting @heatworld with your views.
