Ever since Rihanna and her abusive ex-boyfriend, Chris Brown, got back together, Rihanna has been throwing subliminal shots at his girlfriend, Karrueche Tran, on her Twitter page.

But Karrueche struck back with a diss of her own. When Brown tweeted a photo of himself cooking a meal for Karrueche in February, Karrueche tweeted a pic of the food that Brown prepared for her. The caption read “Yup… Get mad!”

In retaliation, Rihanna tweeted the above picture of a package of rice cakes wearing sunglasses and hoop earrings. The caption below the pic read: “Ima make u my bitch.”

Rihanna’s Twitter followers made the obvious connection to Brown’s girlfriend.

But if you think Brown is going to defend his main chick (Karrueche), or even try to make the peace between his two women — think again.

The lyrics to Rihanna’s “Birthday Cake Remix” — which Brown hopped on and co-signed — contain a reference to “rice cakes,” which is considered an insult to the Vietnamese. Karrueche is an aspiring model who is part Vietnamese.

So did Rihanna really take it there? Is she being disrespectful and racist because she can’t get her way with Chris? Or is Rihanna just being Rihanna?
