R. Kelly's child pornography trial was adjourned earlier than usual Wednesday due to the 11th hour emergence of a defense witness.

She told jurors she saw the tape for the first time in December 2007, after prosecutors approached her. That first time she wasn't sure it was Kelly and the alleged victim, but she became "110 percent" certain after viewing it again, she said. "The image I saw looked exactly like Mr. Kelly," she said, adding she was "shocked" and "disturbed" by the video. Perryman said she saw the alleged victim numerous times, including when she would come to Kelly's Chicago music studio. She recognized the girl as the one in the video by her cheekbones, as well as by the "distinctive" way she moved her mouth, smiled and talked, she told jurors. SOURCE:EURWEB
