Chris Brown's new girlfriend struggles in Rihanna's shadow

Los Angeles - Karrueche Tran says Chris Brown's previous relationship with Rihanna has made things difficult.

The rapper's on/off girlfriend has opened up about her romance with the star - who was released from jail on  2 June after serving 108 days for violating his probation, which stemmed from his assault on the Stay hitmaker in 2009 - and admitted his ex-lover's fans made things difficult.

Speaking on Just Keke, she said: "In this case my boyfriend is a celebrity whose ex-girlfriend is an even bigger [celebrity]...so, I'm not only am I fighting a battle with her, I'm fighting a battle with her 14 million fans or however else.

"So, imagine how that feels for me when I gotta get on Twitter and I see a whole bunch of stuff...they make up all kinds of crazy stuff and it's like they know nothing about me.

"But, you know, because they know nothing about me, because I stay so mute sometimes, that leaves open space for them to say whatever they want."

Karrueche insisted she is trying to stay positive and level-headed in the middle of the love triangle, but admitted it has been difficult.

Asked what the hardest part has been, she responded: "Um, jeez. I guess I would say the heartbreak because it was a real situation."
