Chris Brown's girlfriend 'fighting a battle' with Rihanna fans

Chris Brown's on/off girlfriend Karrueche Tran has said that the singer's previous history with Rihanna has made things difficult for her.

Tran has opened up about her romance with the star - who was released from jail on June 2 after serving 108 days for violating his probation, which stemmed from his assault on the 'Stay' dinger in 2009 - and admitted his ex-lover's fans have targeted her online.
