Adding more fuel to the rumors they’re seeing each other on the low, Chris Brown and his ex Rihanna were both spotted partying at Greystone Manor last night. People inside the club say they didn’t see them together, and Chris’ girl Karreuche was definitely with him but…could he and Rihanna be playing a major game right now trying to be slick, and funny at the same time?? Hmm! Check out the video of both leaving last night. Breezy has quite the smirk!
