Just a few days after Chris Brown announced to the world that he is newly single at Power 106's annual Cali Christmas Concert in Los Angeles, the "Loyal" singer is going into detail about why he is no longer with Karrueche Tran.

On Saturday night, Brown took to Instagram to accuse Tran of cheating on him with rapper, Drake. He posted a screenshot --- which has since been deleted -- of a tweet he wrote earlier that day about Tran treating him like a "regular n*gga" despite the many sacrifices he made for her during their relationship.

Brown tagged Tran's name in the screenshot and attached a lengthy caption detailing the alleged ways she mistreated him while they were dating. He accuses Tran of only visiting him one time during the four months he was incarcerated and allegedly "taking secret trips to Toronto, going on dates with Drake!"

The singer also slammed Tran for allegedly playing the victim throughout their time dating.

"That ride or die act we have been fooling the world with obviously ain't working," he wrote. "So let's not try to save face for public opinion because I don't need to play victim so people can take my side."

Brown's lengthy Instagram diss to Tran follows her initial Instagram post about being "mistreated" by Brown throughout their relationship, Us Weekly reports.

"I refuse to be repeatedly mistreated especially by someone who claims to love me," she wrote. "That's not love. And if that's what you define as love then I don't want it. Yes, I have not been so smart before in the past but I made a promise to be a better and stronger woman and I'm keeping that promise."

Drake has yet to respond to Tran or Brown's Instagram revelations.

Brown and Tran's recent breakup follows Brown's interview with New York radio station Hot 97 last month where he revealed his plans to start a family with Tran. He also defended Tran last month via Instagram after the co-hosts of "The Real" discussed Brown and Tran's tumultuous relationship.
