Diddy's fate will be in the hands of 12 jurors who will decide if he committed a series of sex crimes over, even as the feds may have lost one of their top witnesses

The jury in Sean "Diddy" Combs' sex trafficking and racketeering trial was not seated as was expected Friday. Instead, it will happen early Monday, with opening statements in the case to follow.

The trial should remain on schedule after the defense suggested that the final 12 jurors and six alternates could ask to be excused after spending a weekend contemplating a role in a major celebrity's fate.
