Diva behavior in pop music these days isn't exactly uncommon, and Mariah Carey is one of the experts at it. But she's also apparently good at playing the Blame Game as well. Witness the debacle at 30 Rock:
"I think honesty is of the first, utmost importance in art... any art. After that comes technique and... after that comes talent. Honesty is first. All the rest of the things are important, too, but they're secondary. Without honesty, I don't care how much technique you have, you have nothing."--Linda Ronstadt
