50 Cent Reunites G-Unit at Hot 97's 2014 Summer Jam concert.

The G-Unit CEO emerged to “Hate Me Now,” all smiles, clearly basking in the moment, as he ran through hits like “I Get Money,” “What Up Gangsta” and early mixtape cuts.

What happened next, however, was truly unexpected (especially considering G-Unit’s veryrecent public disagreements), but 50 actually managed to get Lloyd Banks, Tony Yayo and Young Buck on stage for their first joint performance since 2008, hitting tracks like “On Fire,” “So Seductive” and “I Smell P—-.”

That put the crowd on tilt, but Fif didn’t stop there, also bringing out Fabolous and Yo Gotti for the Animal Ambition single “Don’t Worry ‘Bout It.” In fact, 50 was having so much fun that he didn’t want to leave. Literally. A scuffle on stage didn’t prevent him from taking time to rant about Jimmy Iovine not being his boss. Only when his mic cut off did he unwillingly throw the towel in.
