50 Cent reunited with most of the original G-Unit members at Summer Jam over the weekend, performing a slew of hits with Tony Yayo, Lloyd Banks and Young Buck - though no Game.

The clique were the surprise package after Nas had finished up his set. Fabolous, along with dozens of other guys joined the crew on-stage for the big-reunion though the celebratory atmosphere went south pretty quickly. 

According to XXL, a fight broke out on-stage as G-Unit were performing. Slow from Slow Bucks was apparently angry that security refused to let him join the group on-stage, and Lloyd Banks also looked pretty upset. Fabolous had to calm down and walk Slow off the stage, while Hot 97's Ebro Darden was seen chatting with Bucks to try and placate him. A source at Summer Jam said Slow had problems with one of the crew members of 50 Cent.

Other than that disagreement, Summer Jam was a success at the MetLife Stadium in East Rutherford, with Iggy Azalea, Childish Gambino, Nipsey Hussle and Chinx Drugz performing energetic sets early on. 

French Montana, Nicki Minaj and The Roots played later in the evening, with Drake making a special guest appearance during the Pills n Potion singer's set. 

DJ Mustard rounded off the evening with a DJ set that included his new single 'Down on Me'.
