The jealous singer almost got in a punch-up recently with the aspiring model, and now the arch enemies are sparring over social media – with Rihanna copping accusations of racism on Twitter and Karrueche drawing “Ange v Jen” comparisons on Facebook.

The controversy ignited when Rihanna tweeted a photo of a packet of rice cakes dressed up in sunglasses and hoop earrings, along with the comment, “Ima make u my b—-.”

Many bloggers and tweeters concluded that Rihanna was making a racist jab at Karrueche, who is half Vietnamese.

Another theory is that it may have been a reference to the lyrics in her song ‘Birthday Cake’: Come and get it. Sweeter than a rice cake, cake worth sipping.”

Either way, the apparent response from Karrueche wasn’t pretty.

A screen grab from her facebook page reads: “I win you loose!!! *Nicki voice* I meannnn I got him, you got pictures of him. Buwhaha…”

A friend then commented: “I’m Angelina , you Jennifer. C’mon b–ch, you see where Brad at.”

…Which is in fact a line from Nicki Minaj’s song ‘Stupid Hoe’.
