Katy Perry plans to take aim at Taylor Swift at the Super Bowl with her new song 'She's So Creepy'.

The 30-year-old star intends to debut the song during her eagerly-awaited half-time show and is thought to be a retaliation to Taylor's 'Bad Blood', which appears on her album '1989' and exposes the details of their feud, according to The Sun newspaper.

Taylor has never admitted her song is about Katy, but she's said of the unidentified rival: ''We're straight up enemies. And it wasn't even about a guy!

''It had to do with business. She tried to hire a bunch of people out under me.''

Shortly after those remarks, Katy took to Twitter, referencing the Lindsay Lohan film 'Mean Girls' and writing: ''Watch out for the Regina George in sheep's clothing.''

Although Taylor insists their row is not over a man, the pair have both dated musician John Mayer, 37, in the past.

And over the weekend, Katy and John were spotted enjoying a dinner date at a friend's house, after which he is said to have spent the night at Katy's home.

The news has prompted speculation they have rekindled their romance.
