Taylor Swift denies 'approving' Kanye West's track Famous
Taylor Swift is accusing Kanye West and Kim Kardashian of "character assassination".
It is after Kim posted a series of videos appearing to show her husband talking to the singer about his track Famous.
They claim the footage proves Taylor had approved a controversial lyric about her.
However, the 26-year-old's released a statement saying, "you cannot approve a song you haven't heard".
This is the latest development in a high profile three-way feud involving the world's biggest popstar, rapper and reality star.
Kim had previously claimed she had proof that a "phone convo"about the song had happened, because her husband was filming a documentary at the time.
Now she has uploaded a series of videos to Instagram where Kanye appears to be talking to Taylor via a mobile phone's loudspeaker.
In one of the clips, Taylor says: "I'm really glad that you had the respect to call me and tell me about your concerns about the song."
She also says that she'll talk to him about the song on the Grammy's red carpet.
She says: "If people ask me about it, I think it would be great for me to be like, 'look, he called me and told me about the line before it came out'. Like, 'joke's on you guys, we're fine'.
"You guys want to call this a feud, you want to call this throwing shade, but right after the song comes out, I'm going to be on a Grammy red carpet and they're going ask me about it, and I'm going to be like, 'he called me'."
