Is Katy Perry taking a pop at Taylor Swift with new song 1984?
It seems the long-standing feud between pop princesses Taylor Swift and Katy Perry may be about to escalate as Katy has registered a song called 1984.
It's the year of her birth, which is a bit of a coincidence since Taylor released her 1989 album (based on the year she was born) to great acclaim last year.
The news of the new song comes just weeks after the release of Taylor's Bad Blood video, which is rumoured to be a reference to Katy.
Speaking about the song in September last year, she told Rolling Stone, "For years, I was never sure if we were friends or not.
"She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?'
"She did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy! It had to do with business. She basically tried to sabotage an entire arena tour. She tried to hire a bunch of people out from under me.
"And I'm surprisingly non-confrontational - you would not believe how much I hate conflict. So now I have to avoid her. It's awkward, and I don't like it."
Katy responded by tweeting, "Watch out for the Regina George in sheep's clothing..." referencing the 2004 film Mean Girls.
1984 may well be Katy's revenge song. Both Katy and Taylor have dated American singer John Mayer which is adding fuel to the speculation fire.
