There's not enough money in that, and there are too many other singers who do already do it better. Now that she has been seen pretty much naked, no one is really interested in her voice. If she got up on stage in a modest outfit and sang songs instead of just gyrating, no one would listen or watch.
Who? If that were true I think I would have heard of them. She could have the best voice I have ever heard. Not only quality, but expressiveness. She has real talent. To say I was surprised is an understatement. If you get a chance listen to 'Impossible' from her latest album. It blew me away.
