The couple had dated in 2008 but parted ways after Brown admitted to assaulting Rihanna physically, reported Sun online.
"Jay-Z sees Rihanna like a daughter and has sent his right-hand man Jay to Barbados to see what's going on with her and Chris," a source said.
"She admitted they're pretty much back on and Jay told her they're all behind her and want her to be happy," the source added.
