According to the prosecution's star witness, Lisa Van Allen, not only did R. Kelly film himself having sex with an underage girl, but the Grammy award-winning singer traveled with a duffel bag full of homemade sex tapes at all times. "Wherever he was at, the [duffel] bag would follow," Van Allen said during her testimony on Monday. The 27-year-old witness also claimed she was present for the taping of some of Kelly's sexual encounters with minors.

Van Allen described one instance where she cried during a tryst. "He got upset and said he couldn't watch that. He couldn't do anything with that, with me crying. He stopped the camera," Van Allen said.

The key witness went on to deliver even more damaging information. Van Allen testified that Kelly's business manager, Derrel McDavid, paid her $20,000 each for the return of a sex tape. "Van Allen is an admitted thief and liar who wouldn't know the truth if she tripped over it," McDavid said in a statement. Kelly's attorneys attempted to save the case and excused Van Allen of attempting to extort the R&B singer.

Kelly was slapped with child pornography charges in 2002 for allegedly videotaping himself having sex with a minor. If convicted, the 41-year-old crooner could face up to 15 years in prison.
