Paris, 31, went after photographer Billy Barrera during the wee hours of the morning when she realized he was recording her in the parking garage of the Bootsy Bellows nightclub, trying to snatch his camera from him.
In an exclusive photo obtained by RadarOnline.com, Billy's arm is seen splinted and wrapped up in a bandage while he lay on a hospital bed on Wednesday night.
Billy sustained injuries to his arm, wrist, neck and head, and he plans on filing a police report on Thursday.
"It was 3:30 in the morning, the party was over, and I was just walking through the parking lot to go to the bathroom when I see Paris, so I turned on my camera," Billy told us on Wednesday.
