Taylor Swift insists she simply woke up one day and decided she wanted to be single.

She told 'Access Hollywood': "People say all the time, 'You need to spend some time to yourself and figure out who you are' and I never really understood it until it happened to me.

"I woke up one day and I just realised I'm in New York because I want to be in New York. I cut my hair short because I wanted to. I made a pop album because I wanted to.

"There was absolutely no one else influencing me and that was something I was very proud of.

"Right now, it's not something that I'm interested in. I'm not going to change that part of my life because my life is working right now and I'm happy.

"I'm happy about simple things. I'm happy about friendships. I'm happy about music more so than I've ever been before, so that's the part of my life I am really dead set on not changing."

Taylor's latest song, 'Out of the Woods' - rumoured to be about her previous three-month romance with Harry, which ended in January 2013 - tells the story of her being involved in a death-defying snowmobile crash with an ex-boyfriend.

And the 24-year-old beauty insists she wanted to write the song - which was released on Tuesday and will appear on her fifth studio album '1989', which is out on October 27 - to show people not everything that happens in her life becomes public knowledge.

She added: "Honestly, I think I put that in there because people think they know the exact narrative of the way that my life has gone.

"They think that everybody who reports something is telling the truth. Like, every source is a real friend close to me. When truly, the reason most of the things in the media that are written about me aren't true because none of my real friends would ever talk to the press."
