Chris Brown Dumps Girlfriend Karrueche Tran for Rihanna?

Chris Brown and Rihanna romance rumours have surfaced again claiming that the Love More singer has taken the decision to end his long relationship with girlfriend Karrueche Tran.

It seems matters of the heart continue to mess with Brown's mind as amidst rumours that he and Rihanna have been texting a lot of late, a new report by Radar Online revealed that he has decided to dump Tran, who stood by him during his 90-day stint in rehab.

Brown unfollowed Tran on Twitter shortly after being released from the Malibu treatment center on Thursday.

The day before, she posted the following picture of herself holding a sign that said "Treat your girl right."

A 'renewed interest' in Rihanna is rumoured to be the reason behind Brown's decision to split. Reportedly, the two former lovers have been exchanging flirtatious text messages for weeks now.

Rihanna, meanwhile, has been engaged in a steamy flirtation with rapper, Drake, reports Hollywood Life.

Tran, on her part, has been completely devoted to her boyfriend. She was by Brown's side during his legal troubles, court appearances and she visited him in rehab on holidays.

"She loves him unconditionally no matter the mistakes [he's made]," a source told HollywoodLife.com in January.

But Brown has always remained hesitant towards a serious commitment.

"He's well aware that she wants a commitment from him but he's not ready for all that," another source stated after Brown got out of rehab.
