According to new reports, Rhi Rhi has entered into a war of words with Vietnamese model - and girlfriend of Rihanna's violent ex Chris Brown - Karrueche Tran.

It all kicked off when the Bajan singer posted a picture of a packet of rice cakes, wearing sunglasses and gold earrings with the caption:

"Ima a make u my b**** [sic]", which has been widely perceived as a jibe against Tran.

Rihanna, whose real name is Robyn, also recently teamed up with Brown on a remix of her track, Birthday Cake, singing the line:

"Remember how you did it?, Remember how you fit it?, If you still wanna kiss it, Come, come, come and get it, Sweeter than a rice cake, cake worth sipping."
