Soulja Boy's 26th birthday at a studio in Hollywood reportedly ended in gunfire Friday, leaving rapper and party guest Killa J with a bullet wound to the arm.

According To TMZ, Soulja and his entourage had spotted a black Ford SUV with four men inside as they arrived at the studio, but it wasn't until they checked the security cameras and saw the same vehicle there as they were finishing up that they became suspicious. When Killa J went to see what was going on, the men approached him and demanded that he give them Soulja Boy's Gucci bag.

The source claims that Shots were fired after Killa J did not comply, and was struck by a bullet in the arm, a wound he's expected to recover from. It is said that Soulja and his crew believe the attempted robbery was an "inside job." The police do not have any suspects.
