Report: Rihanna and Chris Brown Reunite On 'Birthday Cake' Remix

It will be three years this weekend since the last time Rihanna and Chris Brown were supposed to both perform at the Grammys. It will also be three years since the violent altercation which ultimately changed both of their lives, professionally and personally.

On Feb. 8, Chris Brown and Rihanna got into a physical altercation which reportedly took place before both were scheduled to perform at the 2009 Grammys. Brown was charged with two felonies after brutally attacking Rihanna, who at the time was his girlfriend. Brown was sentenced to five years probation and six months of community service in Aug. 2009.

On Sunday night, Rihanna and Chris Brown will meet at the 2012 Grammys, as both are scheduled to perform.

It may not be the first time they have seen each other, for it's been rumored that the ex-couple have been meeting up, most recently spotted (separately) at a 2012 Super Bowl XLVI after party at LA's Grewystone Manor nightclub.
