The Beef: 50 Cent vs. Lil Wayne
Why They Had Beef: In 2007, there were a lot of rumors floating around about both artists having diss tracks prepared for one another. 50 released his first in August by dropping "Part Time Love." And then, Wayne responded (inadvertently) when a song called "Louisianimal" leaked in November without his permission. So, 50 fired back the following January with "Play This On The Radio."
How They Made Up: This beef didn't really have any legs since both artists were bickering over, well, nothing. It ended unceremoniously in August 2009 when 50 appeared at one of Wayne's "America's Most Wanted" tour stops.
