Taylor Swift's next 1989 single may be on its way. The singer is following up "Shake It Off" with "Out of the Woods" in five days, if her clue can be trusted.

On Thursday (October 9), Taylor posted a Tumblr-esque photo of a woodsy path, superimposed with the number "5" and the word "woods." Given that hint, we referenced Swift's profile in Rolling Stone last month, where she talks about "Out of the Woods," which the mag reported is about ex-boyfriend Harry Styles from One Direction.

"Every day was a struggle," she said. "Forget making plans for life -- we were just trying to make it to next week." Woof! Sounds like being one-half of Haylor was no fun at all. No wonder she wrote about it, though Swift doesn't come right out and say "Woods" is about Styles.

The song is co-written by fun.'s Jack Antonoff (who also wrote the soundtrack song "Sweeter Than Fiction" with her). In September, Antonoff exuded excitement for the jam, telling fans on Twitter it "is one of the most important things I've ever been a part of."

Swift admitted "Woods" follows a bad snowmobile accident she had with an ex. RS quotes the lyrics: "Remember when you hit the brakes too soon/ Twenty stitches in a hospital room." They both got hurt, but Taylor corrects herself during the interview, saying she ended up "not as hurt."

If you're wondering why the snowmobile accident never made headlines, well, Taylor said she just asked the witnesses to stay quiet.

"You know what I've found works even better than an NDA [non-disclosure agreement]?" Swift said. "Looking someone in the eye and saying, 'Please don't tell anyone about this.' "

And while we don't know much about her relationship with Styles (other than that they went to the Central Park Zoo together and that she returned from a trip with him heartbroken on a boat), that will probably change in the near future. "Out of the Woods" is expected to be out in five days. Monday can't come soon enough.

1989 is out October 27, but fans who went to her 1989 Secret Sessions said they had talked to her about pre-releasing songs. Taylor told them she had some ideas, and this Tumblr post seems to echo that.

As for how we'll get the track, we don't know how Taylor will surprise us. One Twitter user claims it's going to be released on "The Tonight Show," but that's anyone's guess. Another person claimed they knew she was going to release the track on Monday before she posted the hint. That same Twitterer also said it was Track 4. But you know how it goes: twett
