Taylor Swift has debued a new track from her album Red called 'I Knew You Were Trouble'.
Swift is known for penning songs about relationships and ex-boyfriends and this latest tune is no exception.
Lyrics include: "I knew you were trouble when you walked in. So shame on me now. Flew me to places I'd never been, so you put me down."
With a string of famous exes including Jake Gyllenhaal, Taylor Lautner and John Meyer, the jury is as of yet out, on who 'I Knew You Were Trouble' is about.
Just before the new songs premiere, Swift tweeted:
"I Knew You Were Trouble comes out tonight at midnight. Ready to hear more about my romantic misadventures???"
Red will be released in the UK on October 22 and a day later in the US.
