An FBI expert testified today (May 29) in R Kelly.'s child pornography trial that the sex tape at the centre of the case appears to be authentic.
George Skaluba said that his analysis leads him to believe that the images were not computer generated or altered.
The defence has argued that Kelly is not the man in the video and has suggested the R&B star's likeness could have been computer generated.
However, the FBI expert told jurors that the video appears to depict "real people in a real environment," reports the Associated Press.
Earlier in the day, prosecutors told the judge they needed more time to interview the potential 'mystery' defence witness before he can testify.
Kelly faces child pornography charges for allegedly videotaping himself having sex with a minor some time between 1998 and 2000.
If Kelly is found guilty of the charges, he could face up to 15 years in prison.
The Grammy-winning artist is due to release a new album in July.
