Last year, the actor was reported to have been involved in a "full-on fight" with former business associate Breyon Prescott during an Usher show.
Onlookers claim the incident occurred after Jamie invited some of Breyon's friends over to his table, but didn't ask his former pal to join them.
The pair then had a confrontation, before Breyon reportedly punched the actor, who immediately struck him back before friends, including music producer Jermaine Dupri, waded in to help.
Jamie - who was unhurt - was escorted out of the building through a back entrance and accompanied by security guards as he returned to his car.
