Black Rob's cause of death has been revealed

Rob suffered a series of strokes in 2015 and was recently hospitalized for a kidney ailment but the 51-year-old ultimately died of a heart attack.

Rob's former label boss Diddy has caught a lot of heat for not helping his Bad Boy soldier during his years of health issues.

According to a source who spoke to Page 6, the mogul tried to make it right in the end.

“Diddy offered help for Rob, but in the end, sadly, it was too late.”

“But he wants to make sure that Rob is laid to rest with dignity and according to his wishes. He is helping to make the funeral arrangements,” the source added.

RIP.
