More than likely King of the Hill, NY shyt. I want to say that 50 admitted in an interview back in the day he like to take shots and throw jabs at the opps/competition, akin one of his favs Krs-one and being the bully/villain.
Cam was arguably the biggest star on the Roc in 2002, behind Jay. Cam’s crew was big in the same Mixtape arena just like 50 and G-Unit. Competition.
50 and Jay been having their back and forth jabs since 1999. Also Jay was top dog, so it goes back to going at the best.
Aside from the who J-Lo single thing between Nas and 50, I didn’t see anyone mention that In 2002, there were rumors of Nas signing with Murda Inc (he had that ‘Pledge’ song with Ja and Ashanti, and I believe Irv was on radio saying they were going to make it happen). Also I think 50 just wanted to be the third man in a triple threat match with Jay and Nas
R.Kelly - the reports, the sex tape, Best of Both Worlds. 50 loves to be in the fukkery in general.
