Chris Brown's mother reportedly "begged" Rihanna to speak to him in prison.

The Loyal singer has been in custody since March after breaking the rules of the rehab facility he was in. Anger management treatment at rehab was a condition of his probation, which stemmed from his assault of Rihanna in 2009.

The pair reunited in 2012 for an on/off relationship before things ended for good last May.

While they have thought to have gone their separate ways, Chris' mom was reportedly keen for Rihanna to visit her son.

"Chris' mother Joyce begged Rihanna to speak to Chris. He was in a dark place," a source told British magazine Closer. "Rihanna visited him a few times and they had emotional chats. She told Chris she forgave him and wanted him to move on."

Following her romance with Chris, Rihanna struck up a relationship with singer Drake. However, the romance recently ended and it is thought the 26-year-old beauty is unable to fully cut ties with her former beau.

Chris too has dated since his split from Rihanna, enjoying an on/off romance with model Karrueche Tran.

"Rihanna has vowed to be there for Chris. He'll always be part of her life," the source added.

Earlier this month Chris was ordered to spend an additional 131 days in jail after admitting to violating his probation.

The singer was arrested in October 2013 for allegedly assaulting a man in Washington, DC, prompting prosecutors to bring the case before a judge.

Despite him being behind bars, there were rumours in April that Rihanna was carrying Chris' child. Those claims were quickly denied by a source close to the star.

“Rihanna’s not pregnant with anybody’s baby,” the insider told Hollywood Life. “Motherhood is the last thing on her mind these days, like the last! She’s not in a serious enough relationship to even discuss, let alone think about having a child. Sorry, that’s not the case.”
