The 'Wrecking Ball' hitmaker doesn't feel it is right for her to appear at these events just because she's "important and famous".
She told the new issue of ELLE magazine: "[A year ago] I had to do the 'A Very Murray Christmas' premiere, and I will never do a red carpet again.
"Why, when people are starving, am I on a carpet that's red? Because I'm 'important'? Because I'm 'famous'? That's not how I roll. It's like a skit - it's like 'Zoolander.'"
Meanwhile, the 23-year-old singer previously revealed money doesn't make her happy.
She shared: "People in this industry think, I just gotta keep getting more money, and I'm like, What are you getting more money for? You probably couldn't even spend it all in this lifetime. People get more famous, so that they can make their brand more famous, so that they can sell more s**t, so that they can make more money. It's a never-ending cycle.
"Getting more money, having more hits, being the lead in the movie - those things might stimulate you, but they don't make you happy. I've experienced it all already, and I'm telling you firsthand, it doesn't."
And whilst Miley knows she has a lot of people who look up to her, she never wants to be a "conventional role model".
When asked why she decided to create the Happy Hippie Foundation, she explained: "A lot of us are born into some s**t, you know what I mean? Lately, I've been talking a lot about my being gender-fluid and gender-neutral.
"And some people snarl at that. They want to judge me. People need more conventional role models, I guess. But I just don't care to be that person."
