"Shake It Off" hit maker Taylor Swift has revealed she once had a near-death experience.

The 24-year-old country star said in a recent interview with Rolling Stone she was with a former boyfriend when she was involved in a serious snowmobile accident. She and her ex-boyfriend were then hospitalized but she clarified she was "not as hurt."

One of the songs from her upcoming album "1989" is entitled "Out Of The Woods," which she wrote based on the accident with lyrics saying, "Remember when you hit the brakes too soon, twenty stitches in a hospital room."

"You know what I've found works even better than an NDA? Looking someone in the eye and saying, 'Please don't tell anyone about this.' People think they know the whole narrative of my life," she said about why the information about the accident was never leaked.

"I think maybe that line is there to remind people that there are really big things they don't know about," she added.

Another song from "1989" entitled "Bad Blood" is about another female artist who Swift said she was never sure if they were friends or not for years.

"She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life?' Then last year, the other star crossed a line," she explained.

Swift said she and the artist she declined to name "we're just straight-up enemies" and "it wasn't even about a guy. It had to do with business."

On the other hand, she was reportedly referring to Katy Perry, who dated John Mayer after he broke up with Swift.

"Katy and Taylor are the definition of oil and water. They both have completely opposite personalities and Taylor just rubs Katy the wrong way. Katy feels that everything Taylor does is completely fake and annoying and she really doesn't care for her," a source told Hollywood Life

Neither Swift nor Perry has acknowledged the alleged feud.

Meanwhile, while Swift's "Shake It Off" is currently number one on Billboard Hot 100, Perry's "This Is How We Do" whose music video featured her love for Tumblr and her Metamorphosis Music artist Ferras is at number 29, Music Times has learned.
