On Friday, Chris Brown took to Instagram to threaten a Karrueche Tran fan who posted a picture of himself posing with Brown's now ex-girlfriend at the Staples Center after a Lakers game, Bossip reports.

Although the photo of Karrueche and the fan -- whose Instagram handle is mobzpr3ttyboi -- appeared innocent, the suggestive caption underneath the photo might have sparked the outrage from Brown, who quickly responded to the photo with a threat for MobzPr3ttyboi.

In light of Brown's Instagram proclamation last week about Tran allegedly "going on dates with Drake" while he was incarcerated, MobbzPr3ttyboi captioned the photo with the message, "Just know drake ain't the only 1."

Brown then responded to the caption with the threat, "You weak blood..real n**ga been done smacked fire from u."

Brown later commented on the photo again and dismissed the threat as a joke.

Meanwhile, Karrueche has yet to respond to the online debacle between Brown and MobzPr3ttyboi.

Brown's aggressive response to MobzPr3ttyboi might come as a shock to some of his fans since the "Loyal" singer recently announced his newly single status at Power 106's annual Cali Christmas concert in Los Angeles.

Brown then took his recent breakup with Tran a step further and blasted the model on Instagram for hanging out with Drake and playing the victim throughout their relationship.

Brown has since deleted the Instagram post about Drake and Tran and later issued an Instagram apology for "airing out" Tran's business.

Tran has yet to respond to or accept Brown's Instagram apology publicly. However, MadameNoire suggests that Tran is doing great since the breakup and recently signed to model and talent management agency, Wilhelmina LA.
