R. Kelly has just been found guilty on all counts in his federal sex crimes trial ... and could be staring down life in prison.

The jury started deliberating on Friday afternoon, had the weekend off, and took about half the day on Monday to reach its verdict on 9 federal counts ... including racketeering, sex crimes, human trafficking, obstruction of justice and kidnapping.

The trial wrapped a little over a month after it began ... with the prosecution calling far more witnesses than the defense. Kelly's team only called 5 witnesses over a couple of days. Kelly himself never took the stand.
