Pop star Rihanna was reported on Friday to have reunited with her R&B singer boyfriend Chris Brown , less than three weeks after he was alleged to have assaulted her.

People magazine said Barbados-born Rihanna -- who had hits with "Umbrella" and "Disturbia" -- and Brown were spending time together at one of the homes of hip hop mogul Sean "Diddy" Combs.

"They're together again. They care for each other," People quoted an unidentified source as saying.

"While Chris is reflective and saddened about what happened, he is really happy to be with the woman he loves," the source said in a report on People's website.
