I Think they meet through music and liked each others flow..atleast thats what i heard..i also heard that tupac would let biggie sleep on his couch and shit or maybe biggie let pac sleep on the couch either way...
Afeni was on rap city today talking about how Death Row is hella shady and how they didnt pay pac and how they keep trying to do shit with his music without her permission
I remember reading a interview with Treach from Naughty By Nature...he said that he introduced Pac and Biggie to each other for the first time but that they didn't become friends until like a year after meeting each other. Or some shit along those lines. The interview was in The Source sometime around 1997-1999 I don't recall.
