According to a report by Chicago's Sun Times, the couple has re-established their relationship and is living together.
Brown has not reportedly "officially" moved in with Rihanna, but they've had "quite a few nights together," a family friend of the "Disturbia" singer claimed.
The paper's source said the pop star is not afraid of the potential public backlash for reconciling with Brown, saying, "Rihanna still wants him and has told all of us to 'get over yourselves. … I'm with him, so deal with it.'"
However, the source claimed Rihanna and Brown will not go public with their rekindled relationship "for a while."
When contacted by Access Hollywood, a rep for Chris Brown had "no comment."
As previously reported on AccessHollywood.com, Rihanna is gearing up for a live return to the stage in Dubai on May 28.
Rihanna was forced to cancel her appearance at the Grammys on February 8 after an alleged beating by Brown, just hours before. She also canceled dates in Malaysia and Jakarta following the incident.
Brown pleaded not guilty to felony assault and making criminal threats on April 7 in Los Angeles Superior Court.
