The past few weeks have been rife with speculation that Rihanna and Chris Brown have been secretly hooking up with one another. That they were at the same club last night should do little to hush that chatter. TMZ reports that they were both in attendance at Greystone Manor, a club in West Hollywood. Citing folks who were at the club, they note that everyone tweeting about the pair being there said they didn't see RiRi and Breezy making any contact. Had they wanted to, though, they could. Rihanna's restraining order against Chris Brown was lifted a year ago.
