Country music megastar Taylor Swift has debuted her new single online.
Thanks Tay-Tay!
I Knew You Were Trouble is taken from the 22-year-old's upcoming album Red, and follows her worldwide smash hit single We Are Never Ever Getting Back Together.
The track starts with Taylor's traditional guitar and piano-led sound, but by the time the chorus kicks in everything's starting to sound a whole lot more dubstep.
"I Knew You Were Trouble comes out tonight at midnight. Ready to hear more about my romantic misadventures???" Taylor tweeted earlier.
Taylor's new album Red is due for release 22 October.
