That term's definitely got a negative aura to it because people think a diva is somebody with an attitude who demands things all the time. Of course there is that type of diva but my idea of a diva has always been a singer - whether male or female - who gets on that stage and captivates you with their presence and their voice.
I like to go to anybody else's birthday and if I'm invited I'm a good guest. But I never celebrate my birthdays. I really don't care.
