After months of constant speculation and back-and-forth shots via social media, 50 Cent reunited G-Unit during his set at Summer Jam Sunday evening.

50 Cent, Lloyd Banks, Tony Yayo and Young Buck performed their respective hits before singing some of G-Unit's most memorable songs including the infamous "I Smell P****."

The "Hold On" rapper also brought Yo Gotti and Fabolous to the stage to perform some of his tracks from Animal Ambition. With many people on the Summer Jam stage, the excitement of the reunion quickly turned to chaos.

A fight also went down on stage after Slow Bucks was denied entry. Slow reportedly had an issue with one of the members of 50 Cent's very large group, and there are reports that one member had his chain snatched during the altercation.
