Afroman has apologized for assaulting a female fan onstage during a show in Biloxi, Miss., on Tuesday.
The rapper, whose real name is Joseph Foreman, told TMZ in a Skype interview that he would be seeking anger-management rehab.
The "Because I Got High" singer was performing when two women got onstage and started dancing next to him.
Video shows the 40-year-old rapper hitting and knocking one woman to the floor.
Police stopped the show and arrested Afroman, who later paid a $330 bond.
He told TMZ that he didn’t realize the girl was still onstage, mistaking her for a male heckler who had been berating him throughout the performance.
“I thought the girls had already left the stage, and after hearing this guy for a few songs, I thought it was him,” he said.
He also said he was anxious during the show as he hadn’t medicated and “had to walk half a mile to get to the place.”
