Chris Brown and Rihanna again?

It's been three years now after the Chris Brown-Rihanna infamous battery-assault case and rumor has it that the two are hooking up again.

Sources say that the two have been secretly seeing each other for a year now. Someone close to Brown said that every time Rihanna is in L.A., she sees to it that she will drop by Brown's place and spend time with the "Forever" singer.

But Brown's girlfriend, model Karrueche Tran, doesn't mind the rumor and said that Chris is not cheating on her coz she knows he and Rihanna are just friends.
