Rihanna has been criticised for an alleged 'racist' tweet to Chris Brown's girlfriend, Karrueche Tran.
The singer, who has been in the UK promoting latest album 'Talk That Talk'. tweeted a photo of a pack of rice cakes adorned with an earring and sunglasses.
The picture, which included the tagline: 'Ima make you my bitch', is reportedly poking fun at former boyfriend Chris Brown's , half-Vietnamese girlfriend.
The two singers, who dated until Brown's infamous assault on Rihanna in 2009, both posted the new remixes online last month.
The controversial duo's collaboration 'Birthday Cake' has now fuelled recent rumours that they are back together - you can listen to it hear.
