Over the years, the tabloids have had a field day blaring headlines about Houston's alleged drug problems and marital difficulties with now ex-hubby Bobby Brown. But despite her difficulties, Whitney is still viewed by many as the No. 1 diva of her era, and as such, there is still significant interest in her services.

Like many other artists linked with private functions, Houston has denied cozying up to the corporate crowd, but persistent reports state otherwise. It has specifically been alleged that she and Enrique Iglesias followed Christina Aguilera on stage at billionaire Andrei Melnichenko's multimillion-dollar wedding.
