(AllHipHop News) Hot 97’s Summer Jam concert is known for performers entertaining the crowd by bringing out surprise guests. Chris Brown’s set featured a definite unexpected moment when longtime rivals French Montana and 50 Cent stood on the same stage together.

The G-Unit head and the Coke Boys leader have been in a feud for years. The two New York City rappers threw shots at each other this past March after 50 continued his Instagram assault against French’s Bad Boy boss Diddy.

It appears they have been able to reconcile enough since that time to at least share the same space at MetLife Stadium for Brown’s performance. 50 ran through “What Up Gangsta” and “Many Men.” Followed by French hitting his “Hot N*gga (Remix).”
