Singer Taylor Swift says she once dodged death when she was involved in a serious snowmobile accident with an ex-boyfriend.

Swift admitted her life flashed before her eyes when one of her former lover, rumoured to be One Direction singer Harry Styles, lost control of the vehicle and crashed it, which resulted in them both going to hospital, reports femalefirst.co.uk.

Swift has penned new song titled "Out of the woods", about the incident for her forthcoming album "1989".

Speaking about the song and the incident, the 24-year-old said she wasn't hurt before correcting herself, saying: "Not as hurt."

When asked why nobody has ever leaked information about her snowmobile accident, she said: "You know what I've found works even better than an NDA (non-disclosure agreement)? 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 added.
