Miley Cyrus admits not all her relationships have been ‘straight, heterosexual’ ones.

The 22-year-old singer hinted she might be bisexual while launching her new Happy Hippie Foundation to help homeless and LGBT [Lesbian, Gay, Bisexual and Transgender] youth. She declined to elaborate further, but hopes to use her provocative image to promote more important issues in the future.

She did go on to comment on the issue of youth homelessness on the back of recently launching the Happy Hippy Foundation, which seeks to offer support for homeless LGBT youths.

No one should have to hide who they really are, no matter what his or her name, gender or status. That’s why Happy Hippies are here to say that every life is valuable!

The position I’m in, I feel like I’ve got a lot of power. But so many kids don’t feel that way. They’re under their parents’ rule.

When you have all eyes on you, what are you saying? And that’s what I had to ask myself a lot. It’s like, I know you’re going to look at me more if my (breasts) are out, so look at me. And then I’m going to tell you about my foundation for an hour and totally hustle you.””

Her Foundation will also launch new music, including a collaboration between Joan Jett and Ariana Grande, to raise awareness of the cause.

It’s not going to be an overnight process. You’ve got to get into a lot of people’s brains and you’ve got to really make this a topic.”

Commenting on her sometimes controversial looks, Cyrus said pushing the envelope sometimes helped her progress causes like the Happy Hippy Foundation.

Cyrus, who recently split from Patrick Schwarzenegger, also admits she struggled with traditional gender expectations when she was younger.

She told Out magazine:

I didn’t want to be a boy. I kind of wanted to be nothing. I don’t relate to what people would say defines a girl or a boy, and I think that’s what I had to understand: Being a girl isn’t what I hate, it’s the box that I get put into.”
