Miley Cyrus launches pro LGBT youth group and hints at bisexuality

The 22-year-old also admits she struggled with traditional gender expectations when she was younger.

Miley Cyrus says not all of her relationships have been "straight, heterosexual".

The 22-year-old singer - who recently split from Patrick Schwarzenegger and was once engaged to 'Hunger Games' star Liam Hemsworth - hinted she might be bisexual while launching her new Happy Hippie Foundation to help homeless and LGBT youth.
