What is a diva?

A celebrated female singer, who because of her vocal treasures and occasionally acting abilities - if someone has both, bring ear plugs with you for her performance after - receives prolonged ovation, numerous curtain calls, people standing in line for her autograph, being bothered in her private life in public places. In my opinion Maria Callas was the penultimate diva, nobody could reach her level until 2008. For me she was the eternal diva.
