Rihanna Vs. Karrueche?

Is Rihanna beefing with Chris Brown's current girlfriend Karrueche Tran?

After twitpic-ing a photo of a bag of rice cakes with gold earrings and black shades, which many interpreted as a jab at Karrueche's half-Vietnamese heritage, now it looks like Rihanna was the subject of some digs Tran posted on Facebook.

“I’m Angeline [sic], you’re Jen. C’mon you see where Brad is at,” Karrueche posted.
