US pop star Taylor Swift has dropped a new track called Out Of The Woods.

The song is reportedly another ditty referring to her short-lived relationship to One Direction member, Harry Styles.

The singer posted the full lyrics of her new song on her Tumblr account. While the full track can be listened to here.

Swift's 2012 song, I Knew You Were Trouble, has already been rumoured to be about the bad boy.

"This song (Out Of The Woods) is about the fragility and breakable nature of some relationships," Swift says in a YouTube video where she sits down to talk about the song.

"This was a relationship where I was kind of living day to day, wondering where it was going, if it was going to go anywhere, if it was going to end the next day," she says.

"It was a relationship where you kind of never feel like you're standing on solid ground."

The 24-year-old singer said the feeling she got from this kind of relationship was excitement but also extreme anxiety.

"This song sounds exactly like that frantic feeling of anxiety and questioning, but it stresses that even if a relationship is breakable and fragile, and full of anxiety, it doesn't mean that it isn't worthwhile, exciting, beautiful and all the things that we look for," she says.

The song was co-written by Jack Antonoff, guitarist with the band fun. who is also known for his recent solo project, Bleachers.

#OutOfTheWoods was the top trending item on Twitter in Australia, proving popular with her fans Down Under.

It's the second song from Swift's upcoming pop album, 1989, due out later this month.

Shake It Off, her first single from the album, was a No.1 hit in the ARIA singles charts.

Swift is due to perform on The X Factor Australia grand final on Monday night.
