The pop star told Marie Claire that her years of working on the Disney Channel show Hannah Montana gave her a false sense of what a young woman is supposed to look like.
"I was made to look like someone that I wasn't, which probably caused some body dysmorphia because I had been made pretty every day for so long, and then when I wasn't on that show, it was like, Who the f**k am I?" she told the magazine.
She also talked about the outfit she had to wear to play Hannah from 2006 to 2011. "From the time I was 11, it was, 'You're a pop star! That means you have to be blonde, and you have to have long hair, and you have to put on some glittery tight thing.' Meanwhile, I'm this fragile little girl playing a 16-year-old in a wig and a ton of makeup. It was like Toddlers & Tiaras. I had f**king flippers."
The hours on the show were so long and grueling for Miley that her mother considered whether to bring in lights to help treat her daughter's seasonal affective disorder. Crazy, right?
"Every morning, I was getting coffee jammed down my throat to wake me up," said Miley. "I just had to keep going, be tough, be strong. Everything happened to me on that set."
This isn't the only thing Miley spilled to Marie Claire. She also slammed Taylor Swift's "Bad Blood" music video in the interview. She said that she didn't get the whole violence thing, and that it isn't fair that she gets in trouble for showing her boobs while Taylor portrays violence.
