"I heard some girls scream and a crowd start to form with their cellphone cameras out, and I got up and went around and there was Justin singing in the microphone. I didn't see Selena."
"Then after the song, Rob went up and hugged him and yelled for his wife to come up and then the cameras started taking pictures of them," he added. "There were two teenage girls that kept screaming and crying. Even an hour or so later."
