After an amazing six years of repeated delays, finally jury selection is set to begin today (May 9) in  Grammy-winning R&B singer R. Kelly‘s trial on child pornography charges, prompted by a videotape allegedly showing Kelly having sex with a girl as young as thirteen.

It will be a hard sell for prosecutors as the alleged victim, now 23, says it wasn’t her. And Kelly’s attorneys haven’t admitted it’s Kelly in the video. The 41-year-old Kelly faces up to 15 years in prison if convicted.

Prosecutors claim the videotape was made sometime between Jan. 1, 1998 and Nov. 1 2000, and that the girl was born in September 1984. Kelly was indicted on pornography charges June 5, 2002, after the tape surfaced and was sold illegally on street corners and the Internet. Chicago police began investigating after receiving the tape from the Chicago Sun-Times, which said it was sent to the paper anonymously.

Police and prosecutors said their investigation, including interviews with about 50 witnesses, determined Kelly and an underage girl were on the tape, and that FBI forensics experts had determined the tape was authentic.

R. Kelly has a history of being accused of having sex with underage girls and has settled three lawsuits filed in 1997, 2001 and 2002. In third suit filed, the woman claimed that she began having sex with R. Kelly when she was 16, and he forced her to have an abortion. Kelly was also arrested in Florida on child pornography charges after investigators said they found photos of him having sex with a girl. However, charges were dropped after a judge ruled detectives illegally seized the photographs from a digital camera in his home.

Also, documents show Kelly secretly married the singer Aaliyah  – who died in a plane crash in 2001 – in 1994, when she was 15. The marriage later was annulled by her parents.
