Taylor Swift released the fourth track off of her album Red.

We've already heard "We Are Never Ever Getting Back Together,"  "Begin Again," and "Red", and now Taylor has given fans a preview of "I Knew You Were Trouble."

She shared the track on Twitter, and wrote: "'I Knew You Were Trouble' comes out tonight at midnight. Ready to heard more about my romantic misadventures????"

The full album comes out on October 22nd, so it's almost here!

Wambie girls, what do you think of "I Knew You Were Trouble"?

CORRECTION: We originally wrote this was Tay's third single - it's actually her fourth.Thanks to Wambie girls Veronika and SwiftRox for the correction!
