I'm Doing it I'm doing it I'm doing it now

Does anyone know the title of the song that has the lyrics "I'm doing it, I'm doing it, I'm doing it now". "I represent ______ she/he/it was made out in Brooklyn". Something like that. is all I know.

I THINK this is a Notorious B.I.G. song but I haven't been able to find it anywhere.
Does anyone know the name?

LL Cool J - Doin' It

Hope that helps.

Ah! Thanks a lot. I either heard a weird remix with Biggie or I was wayy off.
