Since graduating from the role of Hannah Montana in 2011, actress and singer Miley Cyrus hasn't shied away from expressing her sexuality through performance art—sometimes to downright scandalous effect. That said, it wasn't until 2015 that Cyrus announced she was gender-fluid, meaning she doesn't exclusively identify with one particular gender. In the time since, she's become a passionate and vocal advocate for various LGBTQ+ issues. Her organization, Happy Hippie Foundation, concentrates on youth homelessness, the LGBTQ+ community, and other vulnerable populations.
