What does "Pre Madonna" mean?

[HiMyNameIsEric!]

You must mean 'prima donna'.

If you describe someone as a prima donna, you disapprove of them because they think they can behave badly or get what they want because they have a particular talent.

I've heard it used sometimes, as a figure of speech. However, I have no idea what this term means. Did I spell it right? LOL
