Swift 24, said her life flashed before her eyes when one of her exes lost control of the mode of transport and crashed it which resulted in them both going to hospital, with her then-beau requiring "20 stitches", reported Rolling Stone magazine.
Taylor has penned new song, 'Out of the Woods', about the death-dodging incident for her upcoming album '1989' and in the tune she sings: "Remember when you hit the brakes too soon/Twenty stitches in a hospital room."
On why nobody has ever leaked information about her snowmobile accident, she added: "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. I think maybe that line is there to remind people that there are really big things they don't know about," she said.
