Rihanna has reportedly demanded her ex-boyfriend Chris Brown publicly apologizes for allegedly attacking her in February on an upcoming Oprah Winfrey Show episode.

Sources tell Look Magazine that Oprah Winfrey has been secretly talking with the Umbrella hitmaker after she told the R&B star not to reconcile with Brown on her daily show.

But Rihanna wants her on/off boyfriend to sit beside her on Oprah's sofa. She is rumoured to have asked Brown to not only pay a visit to Oprah but apologise to her on the show.

Sources tell the publication, "Rihanna has been talking to Oprah Winfrey on a regular basis since late February, when Oprah begged her not to take Chris back. She's been having second thoughts about them being back together. Agreeing to go on Oprah's show and tell the world how sorry he is will help make up her mind."

Winfrey aides are denying the story.

Brown is scheduled to be arraigned on making criminal threats and assault charges on April 6.
