Kesha has revealed she is bisexual.

The 'Die Young' singer - who once claimed she had a sexual encounter with a ghost - doesn't care about gender and loves women as much as men.

The 25-year-old star told the February issue of Seventeen magazine: ''I don't love just men. I love people. It's not about a gender. It's just about the spirit that exudes from that other person you're with.''

The blonde beauty admitted she wanted to speak out about her sexuality to stand up for others who are bullied because of their sexual orientation, as well as for her brother, who is bullied in school for having a speech impediment.

She said: ''I'm all about standing up to gay/lesbian/transgender bullying, but it's also about my little brother. He's 13 and he gets made fun of because he has a stutter. I just have zero tolerance for people making fun of others.''

Kesha previously revealed her new track 'Supernatural' was inspired by an erotic paranormal experience.

She said: ''I also have this song called 'Supernatural'. It's about experiences with the supernatural ... but in a sexy way ... I had a couple experiences with the supernatural ... I don't know his name! He was a ghost! I'm very open to it.''
