The Hip-Hop mogul took to Instagram to reach out the Cannon after news broke earlier this week that he was being fired from the massive media company.
"The only way we can change the narrative, educate, and uplift each other is if we do it together. Nick, my brother, I am here to support you fully in any way you need. What we are not going to do is turn our backs on our brothers and sisters when they challenge the system,' Diddy wrote.
He posted the message alongside a photo of the two stars sitting together at a sporting event.
