Rihanna is rumoured that she has been working on a duet with Chris Brown – who was recently arrested for allegedly attacking her.

The pair have supposedly been working with producer Polow Da Don in Santa Monica, reports E! Online. The resulting song is reportedly set to appear on Brown‘s next album.

Rihanna’s attorney recently said that the singer would testify against Brown in court if she is called to be a witness in his assault case, which is set to take place on April 6.

Rihanna has also been working on new solo material in Los Angeles.
