It's one thing to be bi-sexual (which she's gone on record as saying in an interview with Rolling Stone) and another thing to have both male and female genitalia. The hermaphrodite rumor is just something that was probably started by someone who has beef with her. It seems like when people don't like someone the first thing they do is attack their sexuality. Since she's already out on her bi-sexuality they have to make up some physical abnormality. I recall similar accusations against Ciara and Fergie. I don't believe any of them.
