The Promiscuous star believes people should have the freedom to experiment with their sexuality and has no qualms being attracted to the same sex.
She tells European gay magazine Gus: "I'm reading a book about Chinese medicine, which claims that people are inherently bisexual to balance their energies.
"And, in a way, that makes so much sense. As humans we have both male and female energies.
"I believe Kurt Cobain's statement that, in the end, everyone is gay. Everybody should have the freedom to experiment. I believe sexual experimentation is part of human history."
The Fly Like A Bird singer admits she is attracted to women adding: "Absolutely! Women are beautiful and sexy!"
