A home video showing Chris Brown's girlfriend Karrueche Tran clowning Rihanna is quickly making the rounds of social networking websites.
Using a mock Chinese accent, Tran and 2 of her friends taunt Rihanna as her music video for "Hard" plays in the background.
Tran perfectly describes Rihanna's persona ("sexy, but ugly"), and she sticks the knife in and twists slowly by asking Rihanna "why you no have boyfriend?"
If you recall, Rihanna and Chris Brown surreptitiously tweeted each other on Dec. 29, expressing their undying love for one another.
Watch the hilarity after the break!
