Rihanna's original tweet to Karrueche, widely interpreted as a reference to her Vietnamese heritage.

Rumors may be flying that Chris Brown has already started a secret relationship with Barbadian singer and former abuse victim Rihanna, but his nominal girlfriend, Karrueche Tran, isn't going quietly.

Last week, Rihanna tweeted a message that many interpreted as a racist jab at Chris Brown's Vietnamese girlfriend Karrueche. The tweet linked to a photo of a bag of rice cakes dressed up in Karrueche's signature sunglasses and hoop earrings and included the message Imma make you my b----, a thinly veiled reference at Karrueche.

Karrueche shot back, though, posting on her Facebook, I'm Angeline [sic], you're Jen. C'mon you see where Brad is at, referencing the famous Angelina/Brad/Jennifer Aniston love triangle in which Angelina ultimately won out. The quote was in turn a lyric from a censored version of Nicki Minaj's song Stupid Hoe, the two Caribbean female rappers being competitors to each other.

To add insult to injury, Karrueche also retweeted a message by Rihanna's latest Roc Nation rival, Rita Ora, who was Jay-Z's replacement for Rihanna after a falling out that they had after reports that Rihanna got back together romatically, not just musically, with her abusive ex-boyfriend Chris Brown.

But social networking swipes aside, does Karrueche's accusation hold up?

Given recent reports, it seems unlikely that Karrueche is an Angelina to Rihanna's Jennifer. For one, Karrueche has admitted that the two are in an open relationship – something that's hard to imagine with strong-willed Angelina Jolie-Pitt.

But secondly, there are significant rumors going around that Chris Brown is already back together with Rihanna, and that in fact the couple has been together for nearly a year, according to Us Weekly.

Then again, given Chris Brown's abusive past, is being crowned Mrs. Breezy really all that of a prize?
