Sorry but hands down Monica & Brandy need to headline this event. People are getting mad because people think Beyonce should be in the mix but I totally disagree. Beyonce was more of a Michael Jackson type fan not Whitney. Where as Monica & Brandy have studied this woman and known her personally and both can really sing well. Not that Beyonce cant sing because she can blow, just not a Whitney Houston song Im sorry. So hands down Monica & Brandy as well as Kelly Rowland, Kelly Price, Tamia, Deborah, Christina Aguliera, Patti etc. We need real vocalist here because thats what Whitney was not an ass shaker, but one hell of a singer!!!!!!
