Rich the Kid and his entourage were under attack on Tuesday at a West Hollywood studio where Usher was also recording.
Sources say as many as 10 shots were fired. The man who opened fire was allegedly running away from the studio when he started shooting behind him.
Rich, who was the alleged target, was outside when it all went down. Multiple members of his entourage were attacked, including a bodyguard who was pistol-whipped. Usher was not hurt during the incident.
This is the second time Rich the Kid has been attacked in the past year.
