Open Question: Which singer truly deserves to be called a DIVA?

Okay, I think a DIVDA is someone who has a long history of successful hits and albums, who has kept herself strong and beautiful for years, who has not been broken by the press, who has been a good role model and an addition to this world. I want to say Madonna... but Madonna has fallen in my eyes since the Hard Candy. She was a DIVA in Ray of Light, but now days, she's just too "slutty" and too "desperate" to keep the DIVA name. I want to say Celine Dion, but she's been stock in a circle since My heart will go on... She's not reinventing herself and music is too country as of late. So, after considering many, many more, I have came to a conclusion, that in my opinion, a true DIVA, who actually deserves to bare such name is.... SARAH BRIGHTMAN!!!!! She has been in music industry for 30 years! She has reinvented her image from each album, but not only that, she has songs that are oprah, rock, pop, new age, world, classical, etc... She's one of the rare singers who has a variety of styles compiled into one voice. She's just amazing!!!!
