Taylor Swift has opened up for the first time publicly about her experience with an eating disorder.
In scenes from her documentary, Miss Americana, which debuted at the Sundance Film Festival on Thursday night, Taylor revealed that she would often restrict her eating to the point of feeling she was about to pass out on stage.
Taylor, 30, went on to say that she's felt under constant pressure to meet a "fucking impossible" standard of beauty throughout her career.
She also revealed that when her eating disorder was at its worst, she would make lists of everything she ate, exercised constantly, and routinely "wasn't eating."
And while Taylor now accepts she's "no longer a size double 0" and fights the urge to be critical about her body, she still avoids looking at photos of herself in case it's triggering.
Taylor went on to elaborate on the subject further during an interview with Variety in conjunction with the documentary's release and recalled the formative moment that affected her body image for a decade.
"I remember how, when I was 18," she said, "that was the first time I was on the cover of a magazine, and the headline was like, 'Pregnant at 18?' And it was because I had worn something that made my lower stomach look not flat."
She added: "You register that enough times, and you just start to accommodate everything towards praise and punishment, including your own body."
Back in December, Taylor hinted at what was to come in the documentary by opening up for the first time about how she used food as a way of "exerting control" during her twenties.
"I'm a woman, I'm not a coat hanger," she continued. "I need to feel healthy in my life and I need to take pleasure in food and I need to not use my body as an exercise of control when I feel out of control in my life."
Miss Americana will be released on Netflix on Jan. 31. You can read Taylor Swift's full interview with Variety here.
