DAY OF RECKONING...RIHANNA WILL TESTIFY TODAY!!

Day of Reckoning Rihanna will break four months of silence in a Los Angeles courtroom today when she takes the witness stand and testifies about “SMACKDOWN” and the beating she received at the hands of former boyfriend Chris Brown following a dispute last February. Brown has entered a plea of not guilty on felony assault charges in connection with the case.

RiRi is set to take the stand as a witness against Chris Brown in his preliminary hearing, which begins at 1:45 PM PT.

Rihanna's testimony is hugely important. Will she stick to the story she told cops the night of the beating? Rihanna said Brown had beaten her before and the violence was escalating

Also hugely important .... the photos of Rihanna's battered face. We've published one pic graphically showing the brutality of the beating. But we're told that photo pales by comparison to photos taken the next day after the bruising and swelling settled. Those photos will almost certainly be introduced into evidence during the prelim.

The judge has rejected TV or livestream coverage. We'll have constant updates.
