Brown, who was convicted of assaulting the singer three years ago, is said to have visited her house in Los Angeles this week ahead of her interview with TV mogul Oprah Winfrey, reported Sun Online.
"They are getting on really well at the moment and spent time catching up and relaxing. He's watched clips of her interview with Oprah and seems to be touched," a source said.
A section of the interview shows Rihanna in tears over the assault.
"It was humiliating. It was a confusing space to be in because as angry as I was, I just felt like he made that mistake because he needed help, and who's going to help him?," she said in the interview.
The 24-year-old singer ended her relationship with the 'Yeah 3x' hitmaker in February 2009 after he physically assaulted her.
