Is singer Rihanna a bisexual?

Pop singer Rihanna recently made a big headline for her lesbian kiss with rapper Nicki Minaj. Now, the latest buzz about the RnB star is that she is a bisexual and is said to have been confirmed by model Tajah Burton in her latest book 'Low Down Dirty Shame'.

In her book, the Hollywood socialite has claimed that a Barbados singer was involved in a lesbian relationship. But she has denied to reveal the identity of the singer. Tajah Burton's book 'Low Down Dirty Shame' is yet-to-be-published. But some extracts of the book were leaked on the Internet sparking the speculation.

Tajah Burton writes, "We had an amazing connection. We would order food in together, we watched TV together, we did all kinds of stuff. I listened to her music with her. Music is her life. It became a sexual thing. It only lasted a couple of weeks because she was very busy and had a lot going on in her life and we had to be secretive."

The model added, "I would say she's bisexual. It was really exciting. It was unexpected and it was very fun. The sex was really good but there was more to it - we really had a connection. She inspired me and we helped uplift each other."
