The R. Kelly kiddie porn trial has been delayed for more than five years -- so what's another five years?

TMZ is reporting that Kell's lawyers filed a motion today to delay the trial again.

The trial was finally slated to begin on Friday with jury selection. Just last weekend, the Chicago Sun-Times revealed that a witness was going to come forward to testify that she had had a threesome with R. and the alleged underage victim, and we're told that this new info is what's prompting the motion to continue.

--Man please Kells has probably pissed on 18 more teeny boppers since this trial began! Where is Dateline when you need 'em? Chris Matthews would've had this ish wrapped up in 30 minutes start-to-finish!
