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.

A representative of Chris Brown had no comment on the People report. Rihanna's publicist could not immediately be reached.

Brown, 19, a rising young star with a huge teen fan base, was arrested on February 8 on suspicion of making criminal threats against a woman after a late-night altercation in a car.

Los Angeles prosecutors have not yet decided whether to file formal charges against Brown, who performed chart-toppers "Run It!" and "Forever."

A picture of a bruised Rihanna with swollen lips was leaked on the Internet last week, apparently from Los Angeles police files, and added credence to widespread reports that the woman involved was her.

The assault on the eve of the Grammy Awards caused both stars to cancel their scheduled appearances. It sent shockwaves through the music industry and stunned fans of the couple, who had been dating for about a year.

Rihanna returned to her family in Barbados and Brown issued a statement on February 15 saying he was "sorry and saddened" about the incident and was seeking counseling.

People magazine reported earlier this week that Brown telephoned Rihanna on her 21st birthday a week ago.

"He called to wish her happy birthday," a source told the magazine. "They've reached out to each other. It's been mutual."
