The prosecution has rested in the R. Kelly sex tape trial, but not before it called Lisa Van Allen to the stand.

The former threesome partner of R. Kelly and the alleged victim in this case - who prosecutors say was underage at the time of intercourse with the singer - grew emotional yesterday as she recounted several sexual encounters with the R&B superstar and the anonymous other woman, many of which she said were videotaped.

Van Allen also told jurors (as part of more than three hours of graphic and dramatic testimony) that R. Kelly offered her $250,000 to recover a tape of one of the trysts.

R. Kelly: We believe he can fly, right into jail.

Lisa Van Allen added that she first had sex with the R&B superstar and the alleged victim in 1998. That would have made R. Kelly around 30 years old at the time, while Van Allen was about 18 and the alleged victim would have been 14. Gross stuff, indeed.

In a final, disturbing bit of testimony, Van Allen said that R. Kelly carried a duffel bag containing his homemade sex tapes everywhere he went.

"Wherever he was at, the bag would follow him," she said.
