50 Cent is notorious for starting rap beefs. Just this week, the Queens MC engaged in his latest war of words with longtime adversary Fat Joe, and prank phoned Shyne during a press conference call. Since entering the rap game, he's also gotten into it with Ja Rule, Game, Young Buck, Nas, Jadakiss, Cam'Ron, Rick Ross, Lil Wayne and just about anyone who's ever looked at him funny.
But his most interesting industry relationship has been with Sean "Diddy" Combs. Since Fif popped up on the scene on the cusp of Y2K, 50 and Diddy have shared a very strange love/hate relationship. One minute they're performing together, the next they're throwing barbs at one another. To give you a better idea of what we're talking about, we put together a brief history of their various run-ins over the years. Prepare to be thoroughly confused. —Chris Yuscavage
