Los Angeles, Oct 27 (IANS): Singer Rihanna's best friend Melissa Forde is in trouble after making racist comment on singer Chris Brown's model ex-girlfriend Karrueche Tran who is of Asian origin.

Ever since Rihanna and Brown have rekindled their romance Tran's fans have loathed the act and during a similar exchange of messages on image sharing site Instagram, Forde ended up calling Tran a "rice cake" which is mostly made in Asia, reports dailymail.co.uk.

Forde replied to a fan of Tran and defending Rihanna by writing: "You can be rice cake?s friend I don?t give a f***, but keep up all this disrespectful talk and while your fake profile having azz is typing on instagram me Melissa T Forde will be the one knocking on your door asking you to come talk face to face."

Seeing the tension grow, Rihanna decided to tell her best friend to stop by writing on Twitter: " 'Melissa T Forde! Stop it!."

Brown recently dumped Tran to get back with Rihanna.
