In a recent Billboard article, Chris Brown called his frequent collaborators Migos his "real friends and brothers" and added that he would "never hate" on them.

But that may have changed.

Earlier this week, it was reported Quavo was stepping out with Brown's ex Karrueche Tran.

TMZ's Brown sources say the violent and jealous singer is "livid" about Quavo and Tran. He's especially pissed that he was helping Migos promote their album Culture when Karrueche and Quavo may have been secretly together.

Furthermore, Breezy thinks Quavo may have helped orchestrate the restraining order that Karrueche got against Brown in February as a way of legally removing him from the sure-to-be volatile situation.

It should be noted that Brown hasn't publicly commented on the Karrueche-Quavo coupling. Which shows unusual ... restraint.

Here are Brown and Quavo in better times:

Is Quavo a sneak for this?
