So just what exactly is the status of Rihanna and Chris Brown's relationship today? 

Rumors continue to swirl that the superstar couple has called it quits (again).  A source close to the duo has told E! News it's a done deal, they're really broken up.  That same source says the split had more to do with demanding schedules than anything else.  

Both Rihanna and Brown have been spotted out on the town since word of the big breakup.  Rihanna was caught lighting something up in a Hollywood club early yesterday morning, accompanied by an assistant and security.  Chris Brown meanwhile, was in New York City over the weekend in the company of a mystery blonde.
