The Beef: 50 Cent vs. T.I.
Why They Had Beef: In late 2011, 50 made a comment about Tip's 2010 drug charges and said that he thought T.I. should have let his wife Tiny take the rap for them. That led to a month-long Twitter battle between the two.
How They Made Up: Eventually, cooler heads prevailed and 50 and T.I. worked out their differences with a phone call. "We got into it," 50 said later, "and he had a lot of legitimate points."
