You gotta hand it to Chris Brown and Rihanna—they really don’t care about PR. Brownappears to have dumped his girlfriend, Karrueche Tran, in order to pursue a tighter friendship with Rihanna. The two pop stars were spotted in a reported makeout session Monday—inciting speculation that they’re rekindling the romance that ended in 2009,when Brown was charged with assaulting the “Umbrella” singer. "I love Karrueche very much, but I don't want to see her hurt over my friendship with Rihanna,” Brown told CNN. “I'd rather be single, allowing us to both be happy in our lives." What a fella (ella ella).
