Taylor Swift has released the first single off her new album Reputation.
The singer also tweeted a link to the video for Look What You Made Me Do.
It comes after a week long social media blackout where she removed all her previous activity.
In the new single she declares the old Taylor is “dead”.
Using a phone effect on the track, she says: “The old Taylor can’t come to the phone right now.
“Why? ‘Cause she’s dead.”
Within an hour of its release the video had already racked up almost 500,000 views on Vevo.
Reputation is Taylor’s sixth studio album.
It’s exactly three years since her fifth studio album 1989.
Fans are divided on who exactly Taylor is taking a pop at – is it Katy or Kanye?
“I don’t like your little games/ I don’t like your tilted stage,” she sings.
“The role you made me play: of the fool/ No, I don’t like you.”
Kanye famously used a tilted stage on his recent Saint Pablo tour.
It’s believed that Bad Blood was written about Katy Perry, although Taylor Swift has never confirmed it.
So has this feud continued?
Katy’s latest single Swish Swish, in which she teamed up with Nicki Minaj, is rumoured to be about Taylor Swift.
She released her video on Thursday.
Katy Perry is due to perform at the VMAs this weekend, but the question is – will Taylor be there too?
