Chris Brown Splits With Karrueche Tran For Rihanna

Just when you thought their story was over and done with!

Chris Brown can't seem to decide between two women, and he has apparently switched sides yet again! The much maligned singer has reportedly dumped current lady love Karrueche Tran to rekindle a past romance with ex-girlfriend Rihanna.

This comes as sort of a surprise since it was Tran who stuck with Brown during his tumultuous legal issues and even his 90-day rehab stint, where he'll remain for two more months with his bipolar disorder diagnosis at the center of it. Despite all that's going on, Chris received a glowing report from his rehab facility and he is working on a duet with pop's newest star Ariana Grande, so it seems like things are going in his favor.

Rihanna has been recently linked with Drake yet again ... maybe that's what made Breezy come running back? And wonder how Karrueche's handling all this?

Who knows, but Rihanna has been working it across the pond in Paris for fashion week ... click the gallery below for more photos of the R&B superstar looking fierce at Jean Paul Gaultier and Commes de Garcons!
