First, id like to say that she is NOT an opera singer. She was a child that was overexposed and was more like a novelty because she could PRETEND to sing. I am a professional opera singer and she has been the butt of jokes for years, her and that idiot that was married to Andrew Lloyd Creepy. Calling her an opera singer is like calling Hanson Hard Rock, sure they use electric guitars and drums and know how to play power chords but it definitely is NOT Rock.
If you wanna hear a real female opera singer go to your local opera house or pick up some classic Maria Callas, Tebaldi, Bidu Sayao, or even some Renee Fleming.
