Music Banter - Looking for the name and singer of an older song

When Billy Jean came out by Michael Jackson, someone else put out I guess you would call it "old school rap" song. She was supposed to be Billy Jean telling her side of the story. I love this song and do not remember who sang it, or even it's true title. I haven't heard it in a bazillion years. Desperately trying to find it.

The chorus goes : Superstar, you know just who you are, you are. And the last line goes something like: ...if you don't want no trouble, if you don't want a scene, tip your hat (something, something) cuz I AM BILLY JEAN!

I know more lyrics if anyone needs them to jog the memory.

I have been looking for this song for many years without any luck. I would appreciate any and all help on the matter.

Thanks in advance,

Karyn
