Pre Madonna is actually a mis-spelling of the word 'prima donna' which is a term for people who are tempermental, or a person who takes adulation and privileged treatment as a right and reacts with petulance to criticism or inconvenience.

Pre-Madonna is actually the name of a record that was produced by Stephen Bray in the late 1990's without Madonna's permission. It included songs, rights owned by Bray, that Madonna recorded before she went to the 'big leagues'.

Lol.... I'm full of useless facts...
