A diva is the opposite of a backup singer. If she happens to be in a band, she becomes the band. And last, VH1 standards suggest that age places the final diamond in the diva tiara. Divas have pasts. Divas are strong.
Divas are huge, huge presences.
And, most important, divas have survived the tests of age. To be blunt, not so well. D'Angelo has the body. The Backstreet Boys have the blind adulation of fans. Sting has the singular name.
