Miley Cyrus Grows Up

For months, Miley Cyrus has dodged questions about her relationship with Justin Gaston. For one, she's 16 and he's 20. She's a role model to young girls and he's an underwear model.

In the latest issue of Glamour magazine, the teen queen comes clean about dating an older guy, her body, and the temptations of Hollywood. In other words, Miley's growing up. Here's what she told Glamour's Laurie Sandell:

On the four-year age difference between her and boyfriend Justin Gaston:

"I don't feel like I'm doing anything wrong, and I'm ready for people to accept it. My fans already accept it -- they just want me to be happy. And I haven't been that happy in a few years ... working so hard, moving to L.A. from Nashville, going through a bad breakup [with Nick Jonas]. I'm finally happy again, and I think that is reflected in my music and my work. So honestly, I don't feel like there's anything to hide. And I love him so much I don't really care."

On how they met:

My dad introduced us on the "Hannah Montana" set. I looked so bad that day. I was wearing sweats and glasses and we talked. Then he showed up the next day and said, "I can't stop thinking about you. Can I take you to a movie?" When he took me home, I said, "I don't want to get close to you, because I don't know where this is going to go." And he said, "Well, you can't live like that." So we took a three-mile walk, and talked and talked ... Now he's my best friend."

On the pin-thin-body trend in young Hollywood:

"I think it's lame, because it will eat at you forever. I've been at photo shoots where I've tried something on and said, "Oh my gosh, why don't these fit?" But I'll never be a six-foot-tall, 95-pound model; I'm meant to have a little more meat on my bones."

On the temptations of Hollywood:

"In this industry there are so many things that can take over your life: money, alcohol, drugs -- even fashion. People hand you things, and you start to believe life is easy. And it's not like that -- you're not supposed to be the person you play in the movies ... I like keeping my mind as far away from money and the material aspects of my job as possible.

On ending up like Britney Spears or Lindsay Lohan (who also started out as squeaky-clean Disney Stars:

"The last thing I ever want to do is disappoint my parents. My mom's dad died
when she was 18, and if something ever happened to one of my parents, I'd want
them to go knowing I made them proud. I think it's selfish to go out partying all the
time."
